Like you, I have heard, periodicly, about how many creatures become extinct every year---due to loss of habitat, polution, mad cow dung, and a few etc's.
My question is: Dating from the 1800's, have any mollusks become extinct? And does anyone have the last of them?
Other question: Species from the pliestocene are close but different. Did the Pleistocene species become extinct---or merely change as time went on?
