How are we supposed to respond to evolution when scientists say things like this?

Before you copy and paste something from a creationist web site, do you bother to validate that quotes nearly 30 years old are even accurate? You haven't even bothered to explain why you think that these two quotes hold any significance when it comes to a discussion of evolution. You're too busy looking for "gotchas" to throw in the face if "evolutionists". Perhaps you should spend more time learning about the subject you are failing miserably to try and discredit.
