Compare/contrast Lamarck's explanation of evolution with Darwin's theory of evolution by natural selection.
1 answer:
Lamarck's theory postulates that traits are inherited to their descendants, Darwin's theory states traits are given by natural selection.
For Example, the majestic GIRAFFE! :-)
-Darwin's Theory says giraffes with long necks would be better suited for their African Savannah and would live and reproduce better than giraffes with short necks (natural selection). The short neck gene would.eventually die off.
-Lamarck's Theory says crave perfection. Giraffes with short necks would eventually grow longer necks instead of in Darwin's Theory, dying out. He then concludeds his theory that the giraffes with the better genes will get control over the gene pool aka the good genes are used more, but the bad genes don't just die out like in the other theory.
Hope this helps! :-)
