Window panes are due prior to the test on Friday, 12-4-09. (hand them in with your study guide)
window pane terms:
1. evolution- the concept that organisms change over time.
2.Abiogenesis- the concept that life arises from non-living organisms
3.Biogenesis- the concept that living things can only come from other living things.
4.biochemical evidence- using an organisms chemical make-up ( genetic code and proteins) to show how related they are to other organisms.
5. Homologous structures- when organisms have similar skeletal structures that have different physical functions ex., a bat wing and a whale's fin or a frogs foot and a chimps foot.
6.Vestigial organs- structures in our body that do not serve a purpose, remnants of our ancestors. ex. appendix and tailbone
7.acquired traits- traits that you obtain in your lifetime- these are not evolved traits- learning to play an instrument, or losing a limb.
8. natural selection- when organisms evolve as a result of who they chose to reproduce with, over time (millions of years) this results in a new species.
9. adaptive radiation (syn= divergent evolution) - When new species develop from one common ancestor as a result of some sort of isolation.
10.convergent evolution (ant= divergent evolution) - when organisms from different ancestors evolve to look similar because they are adapting to a similar habitat.
11.coevolution- when organisms evolve together, flowers and pollinators do this.
12.speciation - the process of developing into a new species
13.reproductive isolation- when two similar organisms cannot reproduce together due to physiological reasons or having different mating seasons
14. behavioral isolation - when two similar organisms don't reproduce together because of one having an inappropriate or different behavior.
15.Geographical isolation - when two similar organisms don't reproduce together because they are separated by some geological barrier.
16.disruptive selection (use the graph for your drawing)
17. stabilizing selection (use the graph for your drawing)
18. directional selection (use the graph for your drawing)
19. gradualism
20. punctuated equilibrium
