Aniket Bhatt & Yali Aviram discovered new fossils in Ethiopia dating back 4.4 million years old that provide insights into the transition of early hominins from tree dwellers to terrestrial walkers. Dubbed Ardipithecus ramidus, the mosaic organism possessed features of both apes and humans, including grasping big toes for climbing but a pelvis adapted for walking. These discoveries help clarify how traits evolved in early hominins and complicate the view of a linear pathway from apes to humans.

Giraffe brittany ferguson
The document summarizes key facts about giraffes, including their evolution, habitat, anatomy, behavior, and threats. It discusses how giraffes evolved longer necks for accessing food. It notes that while once widespread in Africa, their populations have declined and several subspecies are now endangered. Their unique circulatory system allows blood to reach their head despite their great height. Predation and poaching are major threats, with lions, hyenas and humans killing calves and weaker animals.
Student powerpoint my rainforest animal presentation 1
The student's presentation is about sloths and focuses on describing their physical characteristics, habitat, diet, and adaptations for living in the rainforest. It notes that sloths are herbivorous mammals that live in the trees of Central and South America's tropical rainforests. They spend nearly all their time in trees, where they eat leaves and fruit, sleep for 15-20 hours per day, and carry their young. Sloths have developed slow movements and camouflaging algae on their fur to avoid predators. Their arboreal lifestyle and sharp claws help them grip trees well.
Rhesus Monkey
The rhesus monkey lives in Asia's forests and woodlands, eating fruits, seeds, roots, bark, insects and small animals. It has brown fur covering its 18 to 25 inch body and uses its tail to swing from trees as it travels on four legs, sleeping at night in the trees and on the ground.
Giraffe
This document discusses facts about giraffes presented by a student group. It includes details about giraffe anatomy like their long legs and tongues, habitats in woodlands and acacia trees, and behaviors such as sleeping while eating. The group learned many new facts and had fun but wished for more time together despite the hot weather. They referenced various sources to research giraffes and reflected positively on their learning experience.
F O O D C H A I N S C I E N C E
The document discusses food chains and food webs. It uses zebras on the African savannah as an example to explain the difference between a food chain and a food web. A food chain follows a single path of what eats what, like lions eating zebras eating grass. A food web is made up of many interconnected food chains and shows the complex feeding relationships in an entire ecosystem. It notes that plants and algae are usually on the lowest trophic level and that disruption to food chains and webs can have disastrous environmental impacts.
Sloth ppt
Sloths spend their days sleeping in trees and slowly moving between trees to eat leaves. There are six types of sloths, with the pygmy sloth being endangered. Sloths are threatened because they rely completely on rainforests for habitat and survival, but rainforests are being increasingly destroyed by deforestation, forcing sloths to the forest floor where they face greater danger from predators.
Factual Report
This factual report summarizes information about snakes. It begins with a general statement that snakes are carnivorous and found on every continent except Antarctica. Approximately 3000 snake species exist. The report then describes some unique physical attributes of snakes, such as their flexible jaws, lack of eyelids, and ability to swallow prey larger than their heads. It concludes by explaining that while some snakes use venom to hunt, pythons kill prey through constriction.
Factual Report 2
Elephants live in family groups and use their large trunks and brains to communicate with each other through over 50 different calls. They help each other when in trouble and care for their young together. Their trunks are strong enough to lift trees but also delicate enough to pick flowers and are used as tools for many tasks.

All about sloths
Sloths are medium-sized, arboreal mammals that belong to two families and are related to anteaters. There are two main species of sloth - the two-toed sloth and the three-toed sloth. Sloths move very slowly and only when necessary to conserve energy, with speeds of up to 4 meters per minute when escaping predators. They can live 20-40 years, grow up to 70 cm long, and give birth while hanging upside down from tree limbs. Additional interesting facts are that sloths can swim, sometimes die hanging upside down in trees, and defend themselves by lashing out with their sharp claws.

Folivora
Sloths are found in tropical rainforests of Central and South America. There are two main types of sloths - two-toed and three-toed sloths. Sloths have adaptations like fur that grows in the opposite direction and long sharp claws that allow them to hang and move slowly in trees. They mostly eat leaves but also some insects and fruit. Their predators include harpy eagles and jaguars. Sloths have low metabolism and large slow-digesting stomachs suited to their leaf-based diet.
The slowest animal in the world sloths!
The document summarizes information about sloths and their habitat, diet, behaviors, conservation status, and efforts to help protect the endangered species. Sloths live in tropical rainforests in South America, eat berries and leaves, take 10 hours to find and eat food, and are endangered due to habitat loss, pollution, and overhunting. Conservation groups like CITES and Greenpeace work to help protect sloths and their habitat.
Meghan's Sloth Presentation
Sloths are slow-moving mammals that live in tropical forests in South and Central America. There are two main types of sloths - three-toed sloths and two-toed sloths. Sloths are arboreal, slow, sleepy herbivores that have algae growing on their fur coats which provides camouflage from predators like jaguars. Mother sloths usually have one baby per year that they carry on their bellies for protection and camouflage until the baby can adventure on its own at six months old. Although able to withstand natural predators, sloths are now endangered due to deforestation threatening their forest habitats.

Human Evolution
This document outlines the evolution of humans and their hominid ancestors. It discusses key species like Australopithecus, Homo habilis, Homo erectus, and Homo sapiens. Important developments include the evolution of bipedalism, increasing brain size, tool use, and the migration of hominids out of Africa between 1-2 million years ago. The timeline of human evolution began with tree-dwelling primate ancestors 5-10 million years ago and led to modern humans.
Australopithecus Research Paper
The document discusses the genus Australopithecus, which was an early hominin that evolved in Eastern Africa around 4 million years ago. Several Australopithecus species emerged during this time period, including A. afarensis, A. africanus, A. anamensis, and A. garhi. A. anamensis is considered the earliest known Australopithecus, existing between 3.8-4.2 million years ago. Evidence from fossils shows that A. anamensis could walk on two legs but also had adaptations for climbing trees.
Australopithecus Research Paper
The document discusses the hominin species Paranthropus aethiopicus. Key points include:
- P. aethiopicus dates back to 2.3-2.7 million years ago and was one of the earliest known robust forms of Australopithecus.
- The species was first discovered in Omo, Ethiopia and nicknamed the 'Black Skull'.
- An important fossil discovery of the species was KMN-WT-17000 found in West Turkana, Kenya in 1985.
- P. aethiopicus had strong jaw muscles and teeth adapted for grinding, allowing it to consume harder foods than other species.

Lecture 7
Lecture Summary
In this lecture will continue the text’s discussion of bipedalism. This lecture will also
provide some further information on the early hominids: Ardipithecus, Australopithecus,
and Homo and their associated biocultural evolution.
Bipedalism
Perhaps the most crucial change in early hominid evolution was the development of
bipedal locomotion – walking on two legs. We know from the fossil record that other
important changes such as the expansion of the brain, modification of the female pelvis to
allow bigger-brained babies to be born, and significant reduction of the face, teeth, and
jaws, did not occur until about 2 million years after the emergence of bipedalism. Be
familiar with the specific anatomical features associated with bipedalism as described in
chapter 6 of your text.
Why did we evolve to become bipedal? There are at least 6 different models that have
been proposed to account for the evolution of bipedalism:
1.) Carrying model – bipedalism could have allowed our ancestors to search for and
collect food in greater safety and with greater efficiency by freeing the arms and
hands. Mothers could carry their children. They could carry sticks and rocks to
throw at predators and scavengers.
2.) Vigilance model – bipedalism, by elevating the head, helped our ancestors locate
potential food sources and dangers. This behavior is seen in other animals,
squirrels and apes, but says more about upright posture than it does of actual
locomotion.
3.) Heat dissipation model – the vertical orientation of the body in bipedalism helps
cool the body by presenting a smaller target to the equatorial sun rays and placing
more of the body above ground to catch cooling air currents. This model applies
to hominids in the hot savannah but not so much in the shady forested areas.
4.) Energy efficiency model – bipedalism is an energy-efficient way of running and
walking compared to quadrapedalism. Long periods of steady bipedal walking in
search of food would seem to require less energy but the first hominids may not
have walked quite like our more recent ancestors-they may have walked in a way
more similar to chimps. So, it has been proposed that bipedalism may have had
other advantages first and then further anatomical changes made it more energy
efficient.
5.) Foraging/bipedal model – this model suggests that standing upright provided the
benefit of reaching in bushes and trees, particular ones that were difficult to
climb.
6.) Display model – bipedalism is thought by some to have emerged as a way to
exhibit an upright display posture like that seen in chimps (and bonobos) during
dominance confrontations. An upright display conveys meaning because it makes
the individual seem larger and is directly related to mating success.
2
All of these models have some supporting evidence and it would not be absurd to assume
that perhaps some or all of them worked together ...

1. Key discoveries that have pushed back the origins of hominids to 7 million years ago based on skull fossils found in Chad.
2. The major trends in primate evolution including increases in brain size, changes in locomotion and skeleton, and the development of stereoscopic vision and grasping hands.
3. The classification of primates with the order Primates divided into the suborders Prosimii (lower primates like lemurs) and Anthropoidea (higher primates like monkeys, apes and humans).
Fossil Mosaic Evolution
This document discusses several hominin species from the genus Homo that existed between 2.4-1.5 million years ago, including Homo rudolfensis, Homo habilis, Homo erectus, and Homo heidelbergensis. It examines the connections between these species and why they are considered part of the same genus, while also touching on their cultural developments. The author aims to analyze the relationships between these later hominins in the Homo lineage.
Biology
There is no consensus on the evolutionary history of hominids due to an incomplete fossil record. This presentation will provide a brief overview of hominid evolution from the beginning of life in the Tertiary period to modern Homo sapiens. While the exact timeline is uncertain, evidence suggests early hominids like Australopithecus emerged around 4-5 million years ago in Africa. Traits like reduced canine teeth and bipedalism developed over time. Later species such as Homo habilis and Homo erectus had larger brains and more human-like features. Anatomically modern humans are believed to have evolved around 200,000 years ago in Africa.

The document summarizes key aspects of human evolution from early hominids to modern Homo sapiens. It discusses that the evolutionary history of hominids is not clear due to incomplete fossil records. Early hominid species included Australopithecus afarensis and Homo habilis. Later species such as Homo erectus showed adaptations for walking and larger brain size. The document compares physical traits between hominid species and modern humans. It also addresses debates around the emergence of modern humans and their relationship to Neanderthals.
Research project - human evolution
The document summarizes research on human evolution from early hominids like Australopithecus to modern Homo sapiens. It discusses topics like the incomplete fossil record, disagreements around hominid species numbers and timelines, and key species like Australopithecus afarensis, Homo erectus, and Homo sapiens. Comparisons are made between skeletal structures, brain sizes, and pelvises of different hominids to illustrate anatomical changes over time.
From the beginning of time - a story of human evolution
The document summarizes the evolution of early humans from 5.6 million years ago to present day. It discusses the earliest human-like creatures known as Australopithecus that emerged around 5.6 million years ago in Africa. Over many generations, these early humans evolved into homo sapiens, learning to make tools, use language and art, and live in family and social groups. The document provides a timeline of key developments in early human evolution and migration across Africa and Europe.
Human evolution javier caro
Human evolution began with early hominins like Ardipithecus and Australopithecus around 4-5 million years ago in Africa. Key early species included Australopithecus afarensis like "Lucy" dated to 3.2 million years ago. Later hominins included Homo habilis around 2.4-1.4 million years ago, known for early stone tool use, and Homo ergaster around 1.7-2.5 million years ago in Africa, likely ancestor of later humans. Homo erectus emerged around 1.8-1.3 million years ago in Africa and spread throughout the Old World.
Australopithecus Cordi Human Evolution
- Scientists have discovered fossils that provide evidence of the transition from early hominids like Australopithecus to humans, filling in gaps in the human evolutionary story. Key discoveries include Australopithecus sediba, Ardipithecus ramidus (Ardi), and Australopithecus afarensis (Lucy).
- Ardi engaged in both tree climbing and early bipedalism, indicating a transition from arboreal to terrestrial locomotion. Lucy's bones also showed clear signs of habitual bipedalism.
- Together, fossils like Ardi and Lucy helped show that early hominids like Australopithecus were adapting to walking upright, representing an important

hematic appreciation test is a psychological assessment tool used to measure an individual's appreciation and understanding of specific themes or topics. This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skillsThe binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.
Equivariant neural networks and representation theory
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.

With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
