Document Summary

O began with bonnier (swiss ecologist) tried to show that alpine species came out from lower species via environmental selection. Proved this via experiment: took lower elevation plants and placed them to alpine location and he came back in a year and saw that the plants had turned into the closest alpine relatives. This is movement to dessert area (geo) looked for wide-spread perennial plants. Esp. look for potentilla and achillea plants. Particularly interested in translocation of moisture (first mountains more moisture to less moisture and then very dry and cold second mountain top) Eventually did multiple reciprocal transplantation between areas. Ultimately multiple transplantation became inefficient so concentrated on three zones (bottom right of first hill = standford ; mid-range of second left mountain = matheson ; top right side of second mountain = timberline } all shown by dash) What they found was that those in timberline plants only timberline plants grew in that area (no other area)

Imagine that we take a population of horses, split them in halfand place them in completely different environments. The twospecies will evolve separate from each other and because theenvironment is different, the outcome of evolution will bedifferent.

But at what point can you say that these horses have evolvedinto two different species?

(I do know that they would probably go extinct if we conductedthis exact experiment, but this experiment is just to give anexample)

Which of the following were important elements of Mendel's experimental design?

A. Controlled matings and reciprocal crosses
B. Choice of traits that had clear-cut alternate forms (antagonistic forms)
C. Choice of experimental organism
D.The use of pure breeding lines
E. Controlled environment
F. All of the above
