An evolutionary biologist says that evolution is not the survival of the "fittest," but that rather it’s the survival of the "just good enough." What does she mean by this? Explain.

Answer 1

SOLUTION I all-powerful force, wrging as since natural selection can produce amazing adaptations, its tempting to think of it as an all-pon ce wiging organizms on, constantly pushing them direction of progress- but this is not what natural selection is like at all. > Natural selection does not produce perfection. If the genes are good enough', you'll get some offsprings into the next generation. → This is apparent to the populations around us; No population or organism is perfectly adapted. - Evolution is the simple result of variation, differential reproduction & heredity - it is mindless and mechanistic. - The population or individual does not want on the to evolve, and natural selection can't try to supply what an organism needs'. Natural selection just selects among whatever variations exist in the population. The eresult is 'evolution'.
