Document Summary
Lecture 2: introduction to darwinian evolution: big questions in biology. These questions arise from our observations about the natural world. The diversity of different life forms on earth. And the fact that within that diversity there is clusters of similarity. So they are diverse within a certain level of similarity that is different from other organisms prof. Organisms tend to be very well suited to their environments. [in some cases the environment is static ( land), in other cases it s changing (water) ] They can do what they need to do to survive & reproduce in those environments. Even if those environments are incredibly challenging to live in. e. g. crypsis - the ability of an organism to avoid observation or detection by other organisms. [in sophisticated ways] for example a dead-leaf butterfly (kalima inchos) & flatfish. So these are the types of observations that led ppl to ask questions about how we could understand biodiversity.
