HNRS 1007 Lecture Notes - Lecture 13: Hadean, Mesozoic, Eye Color
Document Summary
Lecture by jim ottea (professor of entomology at lsu) He"s talking about keeping yourself open to reconciling the starkly contrasted" ideas of religion and science. I don"t think they contrast- they aren"t mutually exclusive, but. Looking back and trying to explain, instead of experimenting and hypothesizing. Up to 4. 5 billion years ago (hadean period: the beginning of the world), but most of what we focus on in human evolution occurred within the last 200 million years (mesozoic period: the cambrian explosion) In a 12-hour clock, modern mankind takes up the very last slot: 11:59. 99 (2 million years ago) Family: hominid: of all the hominids that have ever existed, only the homo sapiens are left. The human family tree: evolution is less a linear progression and more a branching process, mass extinction events. Periodic events that wipe out most of the populations: frequently ending entire species (like the dinosaurs) More species have gone extinct than exist today.
