The document discusses multiple lines of evidence that support evolution, including the fossil record, comparative anatomy, biogeography, embryology, and biochemistry. It explains how fossils are formed through processes like compression, petrification, and becoming molds or casts, and how fossils are used to relatively or absolutely date organisms. Comparative anatomy examines homologous and analogous structures between organisms. Biogeography and continental drift help explain the distribution of species. Embryology shows that embryos of different species resemble each other at early stages. Biochemistry finds that DNA and proteins are similar between closely related species.

A fossil is the preserved remains of a once-living organism.
Fossils give clues about organisms that lived long ago. They help to show that evolution has occurred.
They also provide evidence about how Earth’s surface has changed over time.
Fossils help scientists understand what past environments may have been like.

Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.

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.

DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.
4. Fossil Record
• Evidence of organisms
from long ago
• Formed in many ways
• Layers of earth
show relative age
of fossils
5. Formation of Fossils
A compression fossil is a fossil preserved in
sedimentary rock that has undergone physical
compression.
6. Formation of Fossils
Petrification is the
process by which
organic material is
converted into stone
through the
replacement of the
original material and
the filling of the
original pore spaces
with minerals.
7. Formation of Fossils
Compression fossils, such as those of
fossil ferns, are the result of chemical
reduction of the complex organic
molecules composing the organism's
tissues. In this case the fossil consists
of original material, albeit in a
geochemically altered state. Often
what remains is a carbonaceous film
known as a phytoleim, in which case
the fossil is known as a compression.
Often, however, the phytoleim is lost
and all that remains is an impression
of the organism in the rock—an
impression fossil.
8. Formation of Fossils
Molds and Casts
In some cases, the original bone
or shell dissolves away, leaving
behind an empty space in the
shape of the shell or bone.
This depression is called a mold.
Later, the space may be filled
with other sediments to form a
matching cast in the shape of
the original organism. Many
mollusks (bivalves, snails, and
squid) are commonly found as
molds and casts because their
shells dissolve easily.
10. Dating Fossils
• Relative Dating—based on where in layers of
rock it is.
– Does NOT assign an exact age
• Absolute Dating—test fossil or sediment
around it to get a date range
– Radiometric Dating—uses radioactive isotopes
• Based on half life—amount of time it takes for half the
substance to decay
• Ex. Carbon-14
11. Carbon 14 Dating
•Carbon dating is used to date archaeological samples to the relative dates that the
sample was from.
•The half-life of Carbon-14 is approximately 5,700 years, and as long as there is traces
of Carbon-14 in something, you can age it accurately.
•After an animal or other living
thing dies, Carbon-14 slowly
forms back into Nitrogen
and returns back into the
atmosphere, but regular
Carbon-12 does not decay
so if all the Carbon-14 decays,
then you can not age that
material
12. Biogeography
Darwin noticed:
– The further away he got from home, the more different
the species were from those he recognized. In particular,
older animal groups often were more widespread.
– The closer (geographically) related animals were, the
more likely they were to be similar.
– The further apart two animals, the more time they've
had to evolve in their own direction.
• Using fossil evidence and continental drift,
the distribution of organisms can be
explained (why llamas occur in South
America and their closest living relatives
(camels) live in Asia).
14. Comparative Anatomy
• Homologous structures—structures that
have a common origin, but may be used for
different things.
• Analogous structures—structures that look
similar, but have different origins (e.g. wings
in birds and insects).
17. Comparative Anatomy
• Convergent evolution—animals that are
different evolve similar structures due to
similar environmental pressures. A classic
example is the body shape of fish, dolphins
and ichtyosaurs (extinct). These animals are
unrelated, yet have very similar body shapes.
19. Embryology
• Embryos show common ancestry.
– For example, gill slits in human embryos.
• Many embryos from totally different species look
identical at various stages in their development.
23. Biochemistry
• All organisms use DNA/RNA and proteins as
basis of inheritance
• Similar species have DNA that is very similar.
This can be used to establish lineages and
other relationships.
• This works even on a larger scale such as
between species.
• Can use DNA as a molecular clock to
estimate when organisms diverged (became
different)
