and what are the other people we need to know for evolution and what was their theory
Darwins was different however.
His theory was that there was variation within a species if an event happened that required a certain trait that was more beneficial then the individuals with those alleles would survive and reproduce passing on those alleles to their offspring whilst the ones who didn't have the right trait died and basically over a really long period of time that beneficial trait would be present amongst that population
Lamarack thought that characteristics that an organism obtains during its lifetime would be passed on to offspring e.g. he thought that giraffes stretched their necks by reaching the branches and that when they reproduced the offspring had the stretched necks.
