|This is a photo of your Zaidy According to Scientists|
When I was a kid I used to go to the "tish" of a lot of Rebbes, and during their "toirelich" they would always mention their "zaidis" .... "my zaidy said this ..... my zaidy said that" ....."my zaidy would have said this"
I would always daydream wondering what they actually looked like ......
Well the mystery is over ......according to these apikorsim ..... this is what they looked like!
Meet your relatives: 540 million-year-old bag-like sea creature without an anus may be humans' oldest known ancestor
Researchers have discovered traces of the earliest known prehistoric ancestor of human beings.
In a finding which calls into question decades of research into human evolution, the creature called 'Saccaorhytus' has been revealed.
A microscopic sea creature that lived 540 million years ago, it has sack-like features created by its elliptical body and large mouth.
Bizarrely the species, which is new to science and was identified from microfossils found in China, showed no evidence of having an anus.
This means any waste material inside its body would have come back through the mouth.
It is also believed the thin-skinned creature - discovered after a study of fossils found in China - moved along the ocean bed by 'wriggling'.
The scientists who carried out the research, including some from the University of Cambridge, believe this creature is now the most primitive example of a so-called 'deuterostome'.
This is a broad biological category that encompasses a number of sub-groups, including the vertebrates.
If the conclusions of the study, published in the journal Nature, are correct, then Saccorhytus was the common ancestor of a huge range of species.
This would mean it was the earliest step yet discovered on the evolutionary path that eventually led to humans, hundreds of millions of years later.
'We think that as an early deuterostome this may represent the primitive beginnings of a very diverse range of species, including ourselves,' said Simon Conway Morris, Professor of Evolutionary Palaeobiology at the University of Cambridge.
