This is a draft cheat sheet. It is a work in progress and is not finished yet.
Fossil Records
shows change overtime
fossils can be dated by a variety of methods: age of rock where the fossil is found, rate fo decay of isotopes (carbon-14), relationship within phylogenetic trees, mathematical calculations from chemical properties/geographical data
if just one fossil turned up wrong, it would disprove evolution |
Comparative Embryology
similar embryological development in closely related species |
|
|
Molecular Biology and Biochemistry
measure of common ancestry
comparing DNA and protein structure: universal genetic code (DNA and RNA), cytochrome C (respiration), hemoglobin (gas exchange) |
Biogeography
related organisms in similar range
geographical distribution of species: species living in the same region tend to be more closely related to each other, species which look similar but are from different regions are often not closely related
convergent evolution: evolving similar solutions to similar "problems" |
|
|
Comparative Anatomy
convergent evolution of structures: similar functions, similar external form, different internal structure and development, different evolution, no evolutionary relationship
analogous structure: similar characteristic but no relationship
homologous structure: similarities in characteristics resulting from common ancestry
vestigal organs: modern animals may have structures that serve little or no function but used to for ancestors |
Artificial Selection
induced evolution
artificial breeding can use differences between individuals to create vastly different "breeds" and "varieties" |
