It's not clear (to me at least) what the difference is between convergent evolution and parallel evolution. [[User:Philip J. Rayment|Philip J. Rayment]] 08:28, 24 May 2007 (EDT)

:Parallel evolution would be when two different species evolve together after a symbiotic relationship had been established, like a parasite and its host.
:Convergent evolution is when two different species who do not share a symbiotic relationship evolve similar traits due to selective pressures of the environment.
:The difference between the two is based on the symbiotic relationship. The examples should provide a difference, whales and fish having similar shaped bodies for moving through water would be convergent evolution whereas a tick and a deer evolving together where the tick is only found on a certain species of deer and has selective traits for that host, such as additional enzymes to help break down a protein found only in that deer species.--[[User:Tims|TimS]] 14:37, 24 May 2007 (EDT)
