OK... sticking my neck out here...
I believe a teacher once told me that giraffes didn't always have long necks, but that at first they were more like okapis. Then they wanted to reach higher leaves, and so over time they grew a longer neck.
My questions:
- is this correct?
- why don't we find fossiles of all the forms between the 'okapi' and the giraffe?
- How long did it take for the giraffe to develop the long neck?
Thanks.
