Richard Lewontin
Richard Lewontin is a scientist who likes to look at different things to help us understand them better. Think of him like a detective who investigates crimes to find out what happened. Only he investigates living things instead of crimes.
He's really interested in studying genes, which are things inside living things that help them grow and work properly. Kind of like the instructions for how to build a Lego set that tells you which pieces to use in what order to build the toy.
Lewontin found out that genes can give different instructions to different living things, even if they look the same on the outside. This is because genes can have lots of different versions, called alleles. Like how one Lego set can make different toys by using different instructions.
For example, imagine two kids who look the same but have different hair colors. This is possible because they have different alleles for hair color in their genes.
Lewontin also found out that even though people might look different, they actually have more in common genetically than different. So, just like how all Lego sets have some pieces in common, all people have some genes in common too.
Overall, Lewontin's discoveries helped us understand how genes work and how they can make living things different from each other, even if they look the same.
