"humans were better-suited for survival than t-rexes"
A bizarre statement, given that the two never existed at the same time.
Yes, it was indeed a meteor that killed almost all the dinosaurs (except a group of theropods that had evolved wings and survive to this day). Evidently the shrew-like mammals of the time were better suited to the post-impact environment. We evolved from them.
- dkokelley 17y agosigh You didn't get my point. I intended to use food requirements and storage as an example to show how the more fit for survival are selected to reproduce. I know that my example was an over-simplification. I was trying to meet the parent half-way so that he would understand.
- rv77ax 17y agoso, every body know that meteor killed almost all the dinosaurs. but no body is telling me ? it's some kind of public secret or what ?
- gort 17y agoApparently. The first major clue is the presence of iridium (a metal common in asteroids) at exactly the right place in the rocks (the Cretaceous-Tertiary or "KT" boundary, dating to 65 million years ago, which is also when non-avian dinosaurs went extinct). That was discovered around 1980 by Alvarez et al. Further research has led us to the Chicxulub crater near the Yucatan Peninsula as the impact site. Now you know.
