When it comes down to it, we paleo-types are forced to deal with genera=
anyway (if we are going to be reliable). A biological species is defined=
by whether the animals in a population will breed under natural conditions,=
and derive fertile offspring; something that is impossible to determine=
from the fossil record. I believe the quote is, "A paleontological genus =
=3D biological species."
Modern biologists often have a very difficult time applying the species=
definition to living groups. They simply can't throw two critters into a=
tank together and see if they will breed, because that violates the=
"natural conditions" rule (can you tell I just had an exam on this ;-) =
Let's face it, if people studying modern animals have trouble telling what=
is a species, how much more difficult is our task. It will take hard work=
and good imaginations to tackle these riddles.
