HUMANS MAY HAVE EVOLVED ON THE BEACH | 2005-08-28
Whales are the only animal for which we have a complete fossil record of its evolution from one species to another.

Whales were originally a furry hooved carnivore, no more at home in the water than a tiger. But the shorelineis where the food is. While all other hooved carnivores died out this one apparently ate fish that washedup, then began to go after them in the water.
Ambulocetus, the "walking whale," looked like a crocodile with fur. That is what the original hooved carnivore evolved into. There are thousands of skeletons of these animals that link them directly to whales. It must have mated and had its offsrping on land and it only swam in fresh water.
Then the ambulacaetus took several evolutionary steps. It adapted to salt water, it adapted to mating and having its offspring on land, and it grew a lot.
Actually later seagoing whales still had their two legs that were useless for anything but holding on while mating. And they all remained hunters long after they became ocean beings.
Eating krill came later, much later.
I have talked about the people who in America long before the Indians. The Indians, of course, killed them and took their lands. My theory of why their travel left few traces is not only time, but also because they probably followed the coastline. A people used to foraging the sea would not care so much about WHICH beach they were traveling across.
The one thing that is always changing historically is the coast. There are towns in England that were there in historical times and are now under sea. They found the dead at Pompeii after they figured out where the seacoast was in 69 BC and looked there for the people who were waiting for ships.
Earlier people had searched the present coaswt because they didn't know it had changed, even though St. Augustine's episcopal sea at Hippo is long since under water.
There is enormous evidence that man made a partial transition to sea life. Even the hairs on our backs are positioned for better swimming. Our lack of hair in general is an adaptation to sea life.
There is a very long list of things man has that are obvious adaptations to water.
Also, dolphins have a huge brain, bigger than ours. They too were once furry animals.
We need to look at ancient, very ancient shorelines to find this critical step in our own evolution. Science only accepted continental drift in my lifetime, so we are very backward in that respect.
