Charles Darwin

Showing 1 to 5 of 5

Heya,

Just wana known if I've got things straight, Charles Darwin came up with the first theory's of evolution right? He travelled for 5 years on HMS Beagle and after that kept pet Pigeon's to watch. He recorded his notes using pictures and notes and had a unique way of looking at things.

Am I right or am I getting confused with some other guy? Well whether he's Charles Darwin or not the guy is sure interesting =].

Bye

I'm pretty sure Charles Darwin studied Finches on the Galápagos islands, and this is how he came up with the theory of evolution, natural selection and adaptive radiation? I think. :)

He also noted how tortosises on different Islands had differnet shaped shells depending on their diet.
His main observations were the variation between what appeared to be a wide variety of bire species but were actually all closley related finches.
He observed

  • offspring generally appear similar to their parents
  • no 2 indviduals are identical
  • organsms have the ability to produce large numbers of offsping
  • populations in nature tend to remain fairly stable in size

His conclusions were

  • there is a struggle to survive
  • better adapted animals survive and pass on their characteristics
  • over time, a number of changes may give rise to a new species

Hope that helps:)
