The oldest human footprints – left more than 1.5 million years ago –

Had something else for first days post but this caught my eye and I thought I’d share with the few who find it interesting.

I can not pretend to understand how a set of footprints can last over that period of time.  It seems too fantastic to believe.

Surely all the rain over all the years should have washed them away long ago. No? 

Oh well, if it’s real it is quite a find.  And something else to consider.  If it’s for real and it appears so, what else is on the discovery horizon?

Something to think about.

Oldest human footprints found in Kenya
The oldest human footprints – left more than 1.5 million years ago – have been discovered in northern Kenya.

Two sets of prints left by Homo ergaster, an early ancestor of modern humans. were found in separate rock layers near Ileret.

Laser scanning revealed that feet have stayed much the same over 1.5 million years and the creature walked the same way as people do today.

The prints bore all the hallmarks of a modern human stride, including an arched foot, short toes, and a big toe that was parallel to the other toes.

As in modern humans, weight was transferred from the heel to the ball of the foot and then to the big toe with each step.

The find is the first of its kind since the famous discovery 30 years ago of footprints dating back 3.75 million years at Laetoli, Tanzania.

These older prints are thought to have been left by the more primitive and apelike Australopithecus.

Although this creature also appears to have walked upright, it had a shallow arch and a splayed big toe characteristic of apes.

The Ileret prints, pressed into solidified layers of ancient mud, consisted of an upper and lower set five metres apart.

The top layer contained three trails – two of two prints each, one of seven prints, and a number of isolated prints.

The deeper layer preserved one trail of two prints and a single isolated smaller print that may have been left by a child.

Scientists led by Dr Matthew Bennett, from the University of Bournemouth in Poole, scanned the prints and compared them with those of modern humans and the Laetoli prints.

They wrote in the journal Science: “The Ileret prints show that by 1.5 million years, hominids had evolved an essentially modern human foot function and style of bipedal locomotion.”

Homo ergaster, often known as early Homo erectus, was the first “human” to have long legs and short arms like modern Homo sapiens.

Various remains of H. ergaster/erectus have been found in Tanzania, Kenya, and South Africa, where human beings first evolved.

Not that very many people ever read this far down, but this blog was the creation of Allan Kelly and his friend Vilmar. Vilmar moved on to his own blog some time ago, and Allan ran this place alone until his sudden and unexpected death partway through 2006. We all miss him. A lot. Even though he is gone this site will always still be more than a little bit his. We who are left to carry on the BMEWS tradition owe him a great debt of gratitude, and we hope to be able to pay that back by following his last advice to us all:

1. Keep a firm grasp of Right and Wrong
2. Stay involved with government on every level and don't let those bastards get away with a thing
3. Use every legal means to defend yourself in the event of real internal trouble, and, most importantly:
4. Keep talking to each other, whether here or elsewhere

It's been a long strange trip without you Skipper, but thanks for pointing us in the right direction and giving us a swift kick in the behind to get us going. Keep lookin' down on us, will ya? Thanks.
