how is lamarck's theory different from darwin's?

lamarck believed species population is limited by starvation, disease, competition, and predation
lamarck believed evolution could happen over a long period of time

why were the different finches on each of the galapagos islands
the weather was nicer for some of birds
the food source best fit their beak
the birds moved freely from one island to the other depending on mating season
competition for space became an issue for the birds
how is a penguin able to survive in the warm, galapagos island weather?
the penguins would pluck their feathers to help them keep cool
they would fly south to the antarctic during the warm weather
they would lose feathers each generation to help them get progressively cooler
they have short, thin feathers to help them survive & swim in their environment

hunted and wore clothes
larger brain
bipedalism
