BIO152H5 Study Guide - Final Guide: Invertebrate, Red Algae, Arthropod
Document Summary
Do the textbook questions (focus on the check your understanding questions throughout the text) in addition to the questions below to adequately prepare for the final. Chapter 24: why do traits have to be heritable in order for evolution by natural selection to occur, transitional forms and vestigial traits have both been used as evidence that species change over time. What about islands promotes speciation: explain why individuals do not change when natural selection occurs. Why or why not: polyploid mutations are an important cause of speciation in plants but not in animals. Why: there are no known fossils o the very first living organisms. Give at least two reasons to explain why this lack of fossil evidence for these first organisms is not surprising: crustaceans and centipedes have fewer hox genes than velvet worms or fruit flies do. Study tables: also review the tables shown in class and the tables from your textbook.
