Hello fish face – a fossil fish reveals the origins of the face

4

Lets face it – without a face no-one would recognise us, nor would we be able to guess what others might be thinking or feeling.

Faces and their subtle degrees of symmetry and expression have defined human beauty and tragedy throughout past millennia of art and drama.

Faces, though, are not uniquely human, but are a shared feature with all back-boned animals (vertebrates), from sharks to squirrels. So when and where did the face first acquire its modern, recognisable shape?

A paper published today in Nature announced that the face had its origins deep within extinct armoured fishes called placoderms.

We are all derived from placoderms

 

Placoderms were really gnarly armoured fishes that ruled the oceans, rivers and lakes of the world from about 440-360 million years ago. They were the first animals to evolve jaws and teeth, a truly landmark event in evolution that denotes the beginning of the lineage leading to sharks, bony fishes, amphibians, reptiles and mammals.

  1. Professor Alice Robert’s Darwin Lecture referred to this; all the evidence is clearly observable in the early stage fetus.

    Not many gaps left now, even for the God bod, and they’re disappearing faster and faster all the time.

    Yippee!

    Hang on to yer hats; especially if they’re funny ones.
