    Amazing discovery.

    The footprints older than feet

    HUMAN-like footprints have been found stamped into an ancient sea shore fossilised beneath the Mediterranean island of Crete.

    They shouldn’t be there.

    Testing puts the rock’s age at 5.7 million years.

    That’s a time when palaeontologists believe our human ancestors had only apelike feet.

    And they lived in Africa.

    'human-like', there are a million ways to get odd footprints in mud. This isn't going to push back 'modern humans' to 6 million years ago, that is when the first fossils of something not an ape and something of human characteristics have been found. Evolution cannot be short circuited by millions of years on the scale of change involved with these species. Just as we will never find a T-rex fossil in the Triassic, or a footprint of one.

    Stories like the OP are interesting though.

    I disagree. Evolution is very poorly understood, we know it happens, but we don't know the rate at which it happens, or the percentage of beneficial mutations. The fossil record is so incomplete that the holes that we could drive trucks through and not ever find a thing are legion.

    Could well be a case of parallel evolution.

    Utterly ridiculous. Evolution is very well understood it is only layman that think it isn't. It's like saying 'we don't know what caused the big bang so physicists are entirely in the dark about the universe'. I find people that have a religious bent tend to try to cast scientific facts and theories as 'well we just really don't know' if there is some area that research is still taking place while at the same time they believe in something for which there is no physical evidence. Don't know who is religious here it is a general statement.

    It's like when they were still filling in the periodic table of the elements. 'Well there are still many elements that they 'think' are out there but they haven't found them so the entire table of the elements is just guessing and we don't really know, the whole thing could be wrong'. Sorry that isn't how it works. Go to ANY local college and talk to a biologist and ask them if footprints that are 'human-like' from 6 million years ago could be human. They'll laugh and then explain why it's impossible.

    But fantasy has it's fans.

    Exactly. To flesh out what you are saying, a species could have evolved some of the expected foot traits of walking upright, and then have gone extinct. Meanwhile, a mountain ridge away, another species with less human-like feet was starting to walk upright, and then led to the human line.

    This discovery seems, to a layman watching science from the outside, to be yet another in a series of discoveries which shows our ancestors' family being more diverse and maybe more widespread than we thought. And no, people, that doesn't upend the evolutionary tree, or even just the story of human evolution.

    Original article ~ Possible hominin footprints from the late Miocene (c. 5.7 Ma) of Crete?

    This is very interesting. Dates are always in question, but this is added to the stack of data points. We need repetition when we find something that claims to be outside the norm of understanding.

    Human evolution in Europe has always been difficult to study due to all the civilization there wiping out the evidence before we can get to it.
