1 Part of STUDY GUIDE FOR EXAM 1 (and comprehensive final): MACROEVOLUTION microevolution vs. macroevolution thousand, million, billion fossil speciation extinction preadaptation=exaptation homology vs. analogy vestigial traits convergent evolution heterochrony Pangaea continental drift What types of information are used to determine phylogenies? About how old is the earth? About how old are the oldest fossils of life? of humans? About how many years difference is there between the age of the oldest prokaryotic vs the oldest eukaryotic fossil? (10s, 100s, thousands, millions, or billions of years?) Are the oldest fossils that have been found prokaryotic or eukaryotic? Which is older, the oldest fossil of simple unicellular organisms yet found or the oldest fossil of more complex multicellular organisms? Were hominids, e.g., humans, contemporaneous with dinosaurs? (In real life, not tv shows.) The relative age of different layers of sedimentary rock and the fossils in that rock were established long ago. Have these relative ages since been corroborated or contradicted by data
