Modern human brains and our ancestors brains are different; Progress made from the discovery of a new enzyme
Unlike our related ancestors, the neanderthal and denisovan, modern humans (homo sapiens) continue to survive until today.
Through recent research, it has been understood that only modern day humans hold a special enzyme that has a large impact on our brains
This enzyme is needed to make DNA and RNA.
Around 60 million years ago, modern humans separated from other human species.
Additionally, inside the amino acid that is within the ADSL enzyme only one thing has change.
It is thought that this one small change has a relationship with how modern day humans brains work.
They conducted the experiment on mice.
When having to find water, mice that held the human ADSL enzyme learned the place where the water was faster than regular mice.
From this, perhaps modern humans could find water and other important resources easier.
and so most modern humans are now holding the special gene of ADSL.
Modern scientists think that this gene allowed for modern humans to easily survive.
This research is an important step to be able to understand the evolution of our brains and our activity.
