Scientists find ‘oldest human ancestor’ – IOTW Report

Scientists find ‘oldest human ancestor’

BBC: Researchers have discovered the earliest known ancestor of humans – along with a vast range of other species.

They say that fossilised traces of the 540-million-year-old creature are “exquisitely well preserved”.

  

Hmm…

The microscopic sea animal is the earliest known step on the evolutionary path that led to fish and – eventually – to humans.

Details of the discovery from central China appear in Nature journal.

The research team says that Saccorhytus is the most primitive example of a category of animals called “deuterostomes” which are common ancestors of a broad range of species, including vertebrates (backboned animals).

Saccorhytus was about a millimetre in size, and is thought to have lived between grains of sand on the sea bed.

 

The researchers were unable to find any evidence that the animal had an anus, which suggests that it consumed food and excreted from the same orifice.

  1. Uncle Al wins the thread (so far, anyway).

    P.S. – “Consuming food and excreting from the same orifice”. Piece of cake when you’ve had too much to drink. Could that be where the term “sh*tfaced” comes from…?

    🙂

  2. “They say that it probably ate by engulfing food particles, or even other creatures.”
    It was 1 mm in size and ate other creatures? I think what they found was a fish turd.
