This document summarizes various forms of evidence that support the theory of evolution through natural selection, including:
1) Fossil evidence shows that organisms on Earth have changed over time.
2) Biogeography and anatomical similarities between organisms indicate descent from a common ancestor.
3) Embryological and biological molecular evidence, such as similar DNA sequences, also support evolutionary relationships between organisms.
4) Analogous and homologous structures provide additional evidence for shared ancestry between species.Lesson 19 evidence of evolution

This document outlines six types of evidence that support the theory of evolution:
1. Anatomical evidence such as homologous organs with the same pattern but different functions, analogous organs that evolved independently to serve the same purpose, and vestigial organs that are evolutionary remnants.
2. Fossil evidence showing that ancient species share similarities with modern species and intermediate forms that show evolutionary transitions between groups.
3. Embryonic evidence that embryos of different but related species resemble each other, indicating their shared evolutionary history.
4. Biogeographical evidence of how species are distributed geographically.
5. Molecular evidence from similarities in DNA and proteins.
6. Other unspecified evidence supporting evolutionCladistic
CladisticEmaSushan

Cladistics is a biological classification system that groups organisms based on shared traits and evolutionary relationships. It aims to trace ancestry back to common ancestors by constructing phylogenetic trees based on morphological and molecular data. Key terms in cladistics include plesiomorphy (ancestral traits), apomorphy (derived traits that define groups), and homoplasy (traits that evolved separately in different groups). Together, analysis of character states helps determine evolutionary relationships between taxa.Ch. 23.2 Evolutionary Changes

The document discusses various types of evidence that support evolution including the fossil record, biogeography, convergent evolution, selective breeding, and homologies. The fossil record shows successive changes over time and contains transitional fossils exhibiting traits of ancestors and descendants. Biogeography reveals patterns of evolution through the geographic distribution of extinct and living species. Convergent evolution involves unrelated organisms developing similar traits for adapting to similar environments, while selective breeding involves human-directed changes in traits. Homologies include anatomical, developmental, and molecular similarities that indicate descent from a common ancestor.Chapt15 Lecture

The document discusses the history of life on Earth based on the fossil record. It describes how the geologic timescale divides Earth's history into eras, periods and epochs based on fossils. Mass extinctions, including those at the end of the Ordovician, Devonian, Permian, Triassic and Cretaceous periods, have affected the history of life. Continental drift and plate tectonics have also influenced the evolution and distribution of species over time. Classification systems group organisms into taxonomic categories like domain, kingdom, phylum and species based on characteristics and evolutionary relationships.Biodiv spesies

1) A species is a group of organisms that can interbreed and produce fertile offspring. This is known as the biological species concept.
2) Speciation is the process by which new species arise from existing species. It occurs through anagenesis, where a population accumulates traits over time to form a new species, or cladogenesis, where a new species branches off from an ancestral species.
3) Speciation increases biodiversity by splitting ancestral species into multiple descendant species over time.Analogous structures
Analogous structuresMuhammad Ahsan Nawaz
油
Analogous structures are structures in different species that perform the same function but were not evolved from a common ancestor. They arose through convergent evolution as species adapted to similar environments. Examples include insect wings and bird wings, fish fins and penguin fins, and human, horse and dolphin limbs. While Carolus Linnaeus originally grouped species based only on appearance, analogous structures show that function, not appearance alone, determines evolutionary relationships, and natural selection leads to convergent adaptations over time.Homologous Structure (Evolution)

This document discusses the differences between phenetic and phylogenetic systems of classification. Phenetic classification groups organisms based only on overall similarity of observable traits, regardless of evolutionary relationships. Phylogenetic classification groups organisms based on their inferred evolutionary histories and relationships. Key differences are that phenetic looks only at character states while phylogenetic considers character evolution, and phenetic produces phenograms while phylogenetic aims to depict genetic and temporal relationships in a phylogenetic system of classification. The document provides examples of cladistic characters used in phylogenetic classification and some challenges, like convergent evolution and lack of fossils.Biological Diversity: a molecular re-analysis

The document discusses taxonomy, the hierarchical classification of organisms based on evolutionary relationships. It explains that taxonomy involves assigning organisms unique Latin names at different classification levels from kingdom to species. Rules are established to ensure taxonomy is universal, unique, and stable. The document also introduces phylogenetic trees or cladograms, which depict evolutionary relationships and can show shared derived characteristics between taxa. Cladograms aim to be parsimonious by implying the fewest evolutionary changes.11u bio 02

Comparative anatomy provides evidence for evolution through the identification of homologous structures, analogous structures, and vestigial structures. Homologous structures are body parts with similar structures but different functions, indicating a close evolutionary relationship. Analogous structures have similar functions but different structures and no direct evolutionary relationship. Vestigial structures are remnants of structures that had a use in ancestral species but serve little purpose in current species.Evolution

1. Cladistics is a method of classifying organisms based on shared derived characteristics and evolutionary relationships rather than physical similarity. It uses characteristics inherited from common ancestors to construct branching cladograms depicting evolutionary descent.
2. Determining whether a characteristic is ancestral or derived is important in cladistics. Ancestral characteristics predate the last common ancestor, while derived traits evolved more recently. Outgroup comparison is used to determine polarity.
3. A cladogram depicts nested clades of organisms sharing synapomorphies not found in outgroups. It shows the pattern of common ancestry and branching of life over time based on inheritance of characteristics from ancestors.Higher taxa and higher category

This document discusses the Modern Synthesis (MS) of evolutionary theory and competing views. It makes three key points:
1. The MS viewed genetics as the underlying mechanism of evolution, with natural selection driving adaptation and diversity. However, some see development and form as more important than genetics alone.
2. The explanatory structure of the MS focused on adaptation over homology, whereas alternative views see plasticity, developmental constraints, and homology as more important.
3. The relationship between genetics and evolution was conceived in two ways in the MS - genetics could explain evolution or vice versa. Some mutations are recessive due to the evolution of dominance as an adaptive buffer against generally deleterious mutations.Select all of the types of evidence that biologists have discovered t.pdf

The document discusses various types of evidence supporting the theory of evolution, including fossil records, embryonic development, molecular data, comparative anatomy, and biogeography. It highlights the similarities across species that suggest a common ancestry and emphasizes that no scientific evidence disproves evolutionary theory. Additionally, it mentions how radioactive dating confirms the Earth's age, allowing for sufficient time for evolutionary changes to occur.Ad

The document outlines key concepts in taxonomy and classification of organisms including:
1. Aristotle's early classification system and why it was replaced.
2. Linnaeus' major contribution of using morphological characteristics to classify organisms into a hierarchical system.
3. Modern taxonomy classifies organisms using a variety of evidence like molecular data and places them in domains, kingdoms, phyla and ultimately species.
4. Phylogenetic trees and cladistics further classification by examining shared derived traits.Taxonomy

The document discusses taxonomy, the science of classifying organisms. It describes early classification systems developed by Aristotle and Linnaeus, and the modern hierarchical system of Domain, Kingdom, Phylum etc. The key aspects of modern taxonomy are binomial nomenclature, distinguishing species by ability to interbreed, and use of genetics, fossils and other evidence to determine evolutionary relationships and create phylogenetic trees and cladograms. Taxonomy has been revised to group organisms into 3 domains: Archaea, Bacteria and Eukarya based on rRNA sequences.Evolution review

The document provides an overview of key concepts in biotechnology including the Human Genome Project, genetic engineering, restriction enzymes, cloning, stem cells, and gel electrophoresis. The Human Genome Project aimed to sequence the entire human genome to understand what each gene does. Genetic engineering uses restriction enzymes to cut and splice genes, allowing creation of recombinant DNA. Cloning involves transplanting the nucleus of a donor adult cell into an egg cell to produce an organism with the donor's genes. Stem cells can potentially treat many health issues. Gel electrophoresis separates DNA fragments by size and charge to analyze DNA samples for uses like DNA fingerprinting for criminal investigations.Biotechnology
