Re: I don't get it
I found this interesting -- and typical:
"Following is a list of the platypus fossils found to date. Unfortunately it is quite a short list, as the Australian fossil record is not particularly rich.
In 1971, two fossil platypus teeth were discovered in the Tirari Desert in South Australia. They are about 25 million years old, and have been named Obdurodon insignis. The modern platypus has only vestigial teeth which are replaced by horny pads when it is still a juvenile. The fossil teeth are similar enough to these vestigial teeth to allow identification, and they show that ancient platypuses had teeth as adults. Since then, central Australia has produced a few more isolated teeth, a fragment of a lower jaw, and a part of a pelvis."
These guys are basing all their facts on 2 teeth, part of a jaw and part of a pelvis! And look at all the assumptions they made on that page from this incredibly sparse evidence.
If you read futher in that article you'll find that the ducked bill actually serves a very valuable purpose...just as I stated.
This is the same basic creature millions of years ago that is today, save a few micro-evolutional fine-tunings.
