: : I was wondering if you could give me some information on the differences between Darwin and Lamarks theories of evolution, in favour of Darwin's theory, as i have to write a persuasive essay on the topic
: As I understand it, Darwin postulated evolution gy "survival of the fittest" meaning that traits that enabled a creature (plant, animal) to successfully procreate, and thus fill an ecological niche, would prosper.
: Lamark on the other hand presupposed that acquired attributes of an individual might be ped on to the offspring. He was basing his evolution upon mechanical, or stimulus-response mechanisms being ped down.
: On (bad) example is that if a giraffe streched it's neck during it's life to get a leaf from a higher point on the tree, this would p on to the offspring, rather than darwin's concept that the Giraffe with the longer neck
: because it had more food available, would be more likely to procreate. This is simplist.
: Note: Lamark's concept works for societies, religions and other mechanistic relationships that build on a foundation and grow, adding attributes.
