Earliest 'human footprints' found

I read Earliest 'human footprints' found, by BBC News. 1.5 million year old footprints were found in Kenya. Footprinst can determine the weight, height, and walking style of modern humans. The earliest footprints were found in Laetoli Tanzania, they were 3.7 million years old. The first footprints stated above suggest that humans were able to hunt and travel for long distances. They walked with the heels of their feet. The second set of footprints stated above suggest that humans walking style was like that of an apes. The archings of the toes between footprints was drastically different. There is very little information about hand and foot evolution in humans. One expert says the reason for this is because carnivores eat the flesh of feet and hands leaving tiny bones behind that were not preserved.

I think fossil are neat. When I was little I wanted to be an archeologist. Not anymore though, an archeologist cannot be one hundred percent sure of anything they find. They cannot be sure of where, how, why, when, or what. Whoever found the footprints in Laetoli, Tanzania cannot be sure of how old the footprints really are. They also cannot be sure if the footprints are really human footprints. It was stated in the article that the footprints were like ape footprints, how does the archeologist know that the footprints are human. He or she does not know.
