Unborn babies have lizard-like hand muscles

Recommended Posts

Babies in the womb have extra lizard-like muscles in their hands that most will lose before they are born, medical scans reveal.

They are probably one of the oldest, albeit fleeting, remnants of evolution seen in humans yet, biologists say, in the journal Development.

They date them as 250 million years old - a relic from when reptiles transitioned to mammals.

It is unclear why the human body makes and then deletes them before birth.

The biologists say the developmental step may be what makes thumbs dextrous. Thumbs, unlike other digits, retain an extra muscle.
