Some genes are extremely old: A new study

A group of scientists from the University of Leicester made an exciting discovery about genes related to learning, memory, aggression, and other complex behaviors. 

They found out that these genes have been around for a very long time, about 650 million years. 

This discovery can help us understand our brains and our complex human nature better.

How it was discovered

These genes are crucial for processes like learning, memory, and even controlling emotions. 

We've known that chemicals like serotonin and dopamine in our brains help with these functions. 

What was uncertain was where these genes came from.

Using computer methods, the researchers figured out that most of the genes responsible for making, detecting, and breaking down these brain chemicals first appeared in a group of animals called bilaterians.

Why it's important

This finding has a big impact on how we understand the evolution of complex behaviors. 

It might have played a role in a time called the Cambrian Explosion when many different types of animals started to appear. 

This discovery could help us learn more about how our brains work and why we behave the way we do.

Dr. Feuda also thinks this could help us understand things like reward, addiction, aggression, eating, and sleep better. 

It's an exciting development that opens up new avenues for research.
