Ecology Evolution

biological evolution

changes in the genes of a population over time

natural selection

mechanism that drives evolution

survival of the fittest

best adapted organisms will survive and reproduce

evolution happens at the … level

population

acquired traits can’t be passed on

true

homologous structures

same origin, different function

analogous structurea

different origin, same function

biogeography

distribution of organisms and their ancestors

adaptation

a beneficial genetic trait

divergent evolution

the process by which two or more related species become more different over time

convergent evolution

the process where different species evolve similar traits due to environmental pressures

the person that discoverred that

hutton and lyell

***use and disuse and wrong

lamarck discovered

malthus discovered

artificial selection influenced the theory of natural selection

true

fitness

how well an organism can survive and reproduce in its environment

comparative embryology

vertebrate embryos develop the same way because…

they share a common ancestor
