Flashcards in Evidence of Evolution Deck (21):
4 main bodies of evidence
Study of ancient items like fossils, bones, etc.
Preserved bone or other trace of an ancient organism. Formed when the dead animal or something of an animal is left behind and buried by sediment.
The _______ fossils are the _______ they are
Deeper ; older
Describing what fossils look like. Can be used with location of fossils to determine information about an organism's ancestors.
Not one generation of first species but gradual progression (all fossils)
Where organisms live
Study if developmental patterns in embryos
Vertebrates in _____ stages of ________ are similar
Early ; development
Comparing how organisms are put together through homologous structures and analogous structures
Structures that are derived from a common ancestor but not the same function and caused by divergent evolution
Evolution toward different traits in closely related species
Structures that look similar but evolved from different structures and caused by convergent evolution
Similar traits in very distantly related species
Remnants of an organism's evolutionary past and has no function
similarities in common biological molecules like DNA or proteins
The greater the _________, the higher the ______ difference I. The compared molecules
Divergence ; %
2 specific areas of molecular biology
Non-functioning sections of DNA (don't code for anything), carried along with functional DNA
Come from distant common ancestor, determine head to tail development in embryos
