1) The earliest forms of life on Earth were likely single-celled prokaryotes like bacteria that existed over 3 billion years ago, as evidenced by fossil records.
2) Darwin noted a lack of fossils from the very early Earth, so he could not speculate on how life first began. However, experiments have since suggested simple organic molecules could arise from inorganic precursors under conditions of the early Earth.
3) It is hypothesized that self-replicating molecules like RNA could have led to the first proto-life enclosed in lipid membranes, eventually evolving into the first prokaryotic cells, though the exact origins remain uncertain.
This is very much a work in progress! I also want to add images of the microscopic organisms (from Micro*scope) and characteristics of their respective habitats as well as video clips from 'extremophile hunters.'

Archaebacteria are the oldest organisms on Earth and are found in extreme environments like deep sea vents or volcanic areas. They are classified into several phyla including Euryarchaeota, which contains methanogens and halophiles, and Crenarchaeota, which contains thermophiles. Archaebacteria are important for studying ancient Earth conditions, producing methane through anaerobic digestion, and synthesizing thermophilic enzymes.
This document provides an overview of a seminar on microbes that thrive in extreme environments. It begins with an introduction to microbes in general, then describes 5 main types of microbes. The bulk of the document focuses on 5 categories of microbes that thrive in extreme environments: thermophiles, which prefer high temperatures; psychrophiles, which prefer cold temperatures; halophiles, which thrive in high salt concentrations; acidophiles, which thrive in acidic conditions; and alkaliphiles, which thrive in alkaline conditions. Examples of microbes in each category are provided. The document concludes with references for further information.
This document discusses chemolithotrophs, which are organisms that obtain energy from oxidizing inorganic or organic compounds. It notes that chemolithotrophs, also called chemolithoautotrophs, were first studied by Sergei Winogradsky in sulfur bacteria. Chemolithotrophs face challenges due to the lower energy availability from oxidizing inorganic compounds compared to organics, and solutions include oxidizing more substrate and using reverse electron flow. The document categorizes chemolithotrophs as aerobic, using oxygen as the terminal electron acceptor, or anaerobic, using other compounds besides oxygen.
This document discusses homeostasis in bacteria. It begins by defining homeostasis as self-regulating processes that allow living organisms to maintain internal stability. It then describes several key homeostatic processes in bacteria, including iron homeostasis, metal homeostasis excluding iron, pH homeostasis, and membrane lipid homeostasis. Iron homeostasis involves specialized proteins that help bacteria absorb and store iron at optimal levels. Bacteria also regulate levels of other metals and can tolerate a wide range of pH through homeostatic mechanisms. Finally, the document presents diagrams depicting microbial interactions that maintain community homeostasis and how sugar consumption can disrupt this balance.

Chemolithotrophs are bacteria or archaea that derive energy from inorganic chemical reactions. They can synthesize organic compounds from carbon dioxide using inorganic energy sources like hydrogen sulfide, elemental sulfur, ferrous iron, or molecular hydrogen. Most chemolithotrophs are found in extreme environments like deep sea vents or volcanoes. They include nitrifying bacteria that play a key role in the nitrogen cycle, as well as bacteria that oxidize hydrogen, iron, or sulfur. The process of chemolithotrophy allows these organisms to act as primary producers in ecosystems where organic material is scarce.
Protists are eukaryotic organisms that are not classified as plants, animals, fungi, or bacteria. They can be unicellular or multicellular. Protists are primarily classified based on their method of nutrition - animal-like protists are heterotrophs, plant-like protists contain chloroplasts and perform photosynthesis, and fungus-like protists decompose dead organic material. Common protists include paramecium, amoebas, euglena and various types of algae. Protists play important roles in ecosystems by recycling nutrients, being a food source, and in some cases causing harmful algal blooms.
This document discusses the challenges of classifying protists, which are eukaryotic organisms that are not plants, animals, or fungi. Protists exhibit a wide variety in their characteristics such as being photosynthetic or motile, unicellular or multicellular, and living in various habitats. They are difficult to classify because some protists share similarities with organisms from other kingdoms. While classification of protists continues to evolve, they are believed to have been the first eukaryotes and some protist ancestors gave rise to plants, animals and fungi based on their evolutionary relationships.
Dinoflagellates are unicellular plankton that belong to the phylum dinoflagellata. They have a unique dinokaryotic nucleus and use photosynthesis to produce food. There are over 20,000 known species of dinoflagellates that live primarily in oceans, with some found in snow. While most are harmless, some cause harmful algal blooms that release toxins dangerous to sea life and humans. Dinoflagellates reproduce asexually through binary fission and have a distinctive top-like spinning motion enabled by their two flagella.

This document provides an overview of animal evolution and diversity from their origin to the Cambrian explosion. It begins by defining characteristics of animals and discussing their basic features and organ systems. It then covers the major evolutionary splits between animals including parazoa vs eumetazoa, radiata vs bilateria, acoelomates vs coelomates, and protostomes vs deuterostomes. Key events like gastrulation and the development of germ layers are examined. The Cambrian explosion brought a dramatic expansion in animal diversity due to the evolution of hard body parts and more complex life cycles and development. Major animal phyla are introduced along with basic rules of biological classification.
The document discusses major geological drivers of evolution including tectonic plate movement, vulcanism, climate change, and meteorite impacts. Tectonic plate movement has caused continental drift and formation of supercontinents like Pangaea, affecting species distributions. Vulcanism causes both local and global climate changes through emission of gases and particles and formation of new land barriers and islands. Climate changes over geological timescales have also impacted evolution. Meteorite impacts have precipitated mass extinctions. These geological forces alter Earth's conditions and drive evolution through large-scale migrations, speciation events, mass extinctions, and adaptive radiations.
The document provides information about zoology and human biology.

The document summarizes the key organic macromolecules found in living organisms:
Carbohydrates provide energy and structure, with monomers like glucose and polymers like starch. Lipids store energy and provide insulation, composed of glycerol and fatty acids. Proteins build cell structures and control functions, made of amino acid monomers. Nucleic acids store and transfer genetic information as DNA and RNA. The document then discusses testing methods for identifying these four major macromolecule types.
This document provides an overview of the classification of life on Earth. It discusses the eight major categories used in scientific classification (Domain, Kingdom, Phylum, etc.). The three Domains - Bacteria, Archaea, and Eukarya are introduced. Key details are provided about the characteristics and impacts of bacteria, archaea, protists, plants, fungi and animals. Examples like photosynthetic algae and disease-causing bacteria are mentioned.
This document provides an overview of speciation and the origin of species. It discusses two main species concepts - the morphological species concept, which is based on observable characteristics, and the biological species concept, which depends on organisms' ability to interbreed. Speciation occurs through isolation of populations, which can be caused by external barriers like geographic changes, or internal barriers like differences in mating behaviors. There are two basic patterns of evolution - anagenesis involves changes within a population, while cladogenesis involves branching into multiple species. Speciation events usually begin with external isolation of populations, but can also occur sympatrically when internal barriers form without initial external barriers.

Lecture 1 Molecular And Cellular Biology Overviewmeminie
Â
This document summarizes the key concepts covered in a lecture on molecular and cellular biology:
1. The basic unit of life on Earth is the cell. There are two main types of cells - prokaryotes and eukaryotes - which differ in their structure and complexity.
2. All organisms on Earth evolved from a common ancestor that lived 3.5-4 billion years ago. Molecular evidence from comparative genetics supports the theory of evolution.
3. Cellular properties and behaviors can be understood through the lens of chemistry. Key biomolecules like DNA, RNA and proteins have digital sequences that can be analyzed using bioinformatics.
This document provides additional practice problems for balancing oxidation-reduction reactions in acidic and basic solutions. The problems cover reactions involving silver, zinc, chromium, phosphorus, manganese, chlorine, iron, hydrogen peroxide, and copper species. Balanced equations are provided as answers for each reaction.
This document summarizes important oxidizers and reducers formed in redox reactions under different conditions. It lists common oxidizing agents like MnO4-, Cr2O7-2, and HNO3 that form reduced products like Mn(II), Cr(III), and NO in acid solutions. It also lists common reducers like halide ions, metals, and sulfite ions that form oxidized products like halogens, metal ions, and SO4-2. The document concludes that redox reactions involve electron transfer between oxidizing and reducing agents, and that acidic or basic conditions often indicate a redox reaction will occur.
The document discusses naming acids. It divides acids into binary and oxyacids. Binary acids contain two elements, while oxyacids contain three elements including oxygen. Oxyacids are named based on their "-ate" ion, with variations indicating one more, one less, or two less oxygen atoms than the reference "-ic" acid. Common "-ate" ions include sulfate, nitrate, chlorate, and phosphate.
Acids have a sour taste, are electrolytes, turn indicators red, and have a pH less than 7. They donate protons and can neutralize bases to form salts and water. Bases have a bitter taste, are electrolytes, turn indicators blue or yellow, and have a pH greater than 7. They accept protons and can neutralize acids to form salts and water. Common acids include nitric acid, hydrochloric acid, acetic acid, sulfuric acid, and phosphoric acid. Common bases include lithium hydroxide, sodium hydroxide, potassium hydroxide, magnesium hydroxide, and calcium hydroxide.
- Researchers studied the genetics of fur color in rock pocket mouse populations, investigating how coat color relates to survival in different environments.
- Two varieties of mice occur - light-colored and dark-colored - that correspond to the two major substrate colors in their desert habitat. The dark volcanic substrates are patches separated by kilometers of light-colored sand and granite.
- Data was collected on 225 mice across 35km of desert, recording substrate color and coat color frequencies. Calculations using Hardy-Weinberg equations estimated genotype frequencies within the populations.
Natural selection and genetic mutations have led to the evolution of different coat colors in rock pocket mouse populations. Mice with dark coats are commonly found on dark basalt rocks, while light-colored mice typically live on light sand and granite rocks. Scientists discovered the mice living on basalt carried a mutation in the Mc1r gene, which controls melanin production and results in dark fur that provides camouflage from predators. Multiple rock pocket mouse populations across different lava flows also exhibited Mc1r mutations leading to dark coats, revealing this gene commonly evolves through natural selection to aid survival.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Â
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
Â
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
