I’m surprised that in the relentless attempt to persuade the ‘Answers from Genesis’ lot – who believe that the earth was created in six days, 6,000 years ago etc. – that they’re talking bollocks, more is not made of the whale.
I dare say most people are aware that whales, dolphins etc. are warm-blooded, air-breathing mammals and not fish, but I wonder how many know that they evolved from four-legged land-living animals. The whale’s nearest land-based relative is the hippopotamus, unlikely as it may seem, and an excellent indication that this is what happened, is preserved in whale skeletons.
This can easily be seen in the Natural History Museum. They have removed the iconic ‘Dippy’ – the skeleton of a diplodocus – from the main hall and replaced it with a skeleton of a blue whale. About two thirds of the way down the spine from the head are two tiny triangular bones, separate but adjacent to the spine. They are all that is left of the pelvis, which being the hinge point of the hind limbs has all but melted away over the millennia. Apparently though, some species of whale do still retain rudimentary hind limbs.
It is a perfect demonstration that evolution really does exist.
