📓 Evolution doodle notes

when a certain species shows relatively no evolutionary change in its body structure over a long period of time

• evolution

• adaptation

• stasis

• mutation

any similarity between a pair of structures, processes, or genes of two different species; three types: anatomical, developmental, & molecular

• homoology

• analogy

• convergence

• divergence

similar in structure, but may have different functions; can be similar in related organisms because they were inherited from a common ancestor; may or may not have the same function in descendants

• anatomical homology

• functional homology

• molecular homology

• developmental homology

states that evolution occurred slowly over a long period of time

• punctuated equilibrium

• catastrophism

• gradualism

• natural selection

study of how organisms spread out around the world

• Biogeography

• Ecology

• Geology

• Anthropology

species placed in the same grouping show similarities in DNA, RNA, and protein; some may share specific sections of DNA that provide evidence that they are related to one another

• molecular homology

• genetic drift

• convergent evolution

• adaptive radiation

involves comparing the embryos of various species; suggest that they have a common ancestor

• developmental homology

• genetic drift

• natural selection

• adaptive radiation

analogous structures are similar in function but DO NOT share a common ancestor or structure

• anatomical analogy

• homologous structures

• vestigial structures

• convergent evolution

all discovered and undiscovered fossils and their placement in rock formations and sedimentary layers; show that life on earth was once different from life found today

• Fossil Record

• Geological Timeline

• Evolutionary Theory

• Paleontological Evidence

an entirely new body structure suddenly appears in the fossil record after a long period of stability

• punctuated equilibrium

• gradualism

• catastrophism

• uniformitarianism
