Evolution window pane list: Due Tuesday (11-22-16)
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.Vestigial organs- structures in our body that do not serve a purpose, remnants of our ancestors. ex. appendix and tailbone
6.acquired traits- traits that you obtain in your lifetime- these are not evolved traits- learning to play an instrument, or losing a limb.
7. 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.
8. adaptive radiation (example = divergent evolution) - When new species develop from one common ancestor as a result of some sort of isolation.
9.convergent evolution (opposite= divergent evolution) - when organisms from different ancestors evolve to look similar because they are adapting to a similar habitat.
10.coevolution- when organisms evolve together, flowers and pollinators do this.
11.speciation - the process of developing into a new species
12.reproductive isolation- when two similar organisms cannot reproduce together due to physiological reasons or having different mating seasons
13. behavioral isolation - when two similar organisms don't reproduce together because of one having an inappropriate or different behavior.
14.Geographical isolation - when two similar organisms don't reproduce together because they are separated by some geological barrier.
15.disruptive selection - when the average members of a species are destroyed. This allows the extreme versions to move in and take over their territory or role in the environment.
16. stabilizing selection - When the average members of a population thrive and become even more successful. This results in the extreme versions being less and less prominent in the ecosystem.
17. directional selection (use the graph for your drawing)- When the members on one end of the extreme become more successful in the environment. This leads in the slow disappearance of the average and the other extreme version.
18.Gradualism- Evolution that occurs slowly over a long period of time.
19.Punctuated Equilibrium-Evolution that occurs rapidly due to some sort of natural disaster or other environmental reason
20.Vestigial structures- structures found in an organism that no longer serve a purpose. ( our appendix, our tail bone)
21.Homologous structures- characteristics which are shared by related species because they have been inherited in some way from a common ancestor. For example, the bones on the front fins of a whale are homologous to the bones in a human arm and both are homologous to the bones in a chimpanzee arm.
22.Analogous structures- characteristics are analogous (also called "convergent"), which means that they serve the same function in different species but they evolved independently rather than from the same embryological material or from the same structures in a common ancestor. An example of an analogous structure would be the wings on butterflies, bats, and birds
