Elephants have a gestation of 22 months!!! Dolphins are 12m, our cat was about 9 or 10 weeks we reckon.
The thing that gets me is that SO many animals look exactly the same up until a certain point, so much so that a turtle is indistinguishable from a chicken which is indistinguishable from a human etc.
Even dolphins apparently develop embryonic lower limb buds which later disappear, a result of their land ancestry. That is mental!
I found this diagram, which I remember seeing a more detailed description of in an old embryology text of mine which I can't find. But it shows fish, salamander, tortoise, chicken, pig, cow, rabbit and human embryos and you can see on the top row they are pretty much exactly the same.
There's a larger version of it here: http://upload.wikimedia.org/wikipedia/c ... awings.jpg
So it's not even mammals who all look the same to start. Bloody reptiles and fish do too
wow that's really amazing
