It is well known that physically characteristics can be passed down the generations. As an example, my brother-in-law looks just like a relative from 100 years ago.
Years ago I met a distant relative who branched away from our family tree in the 1700s. He looked remarkably like my uncle! That was over 200 years ago!
Now, I am no human biologist, but I gather much of our DNA is not used to create us physically. So, I wonder what it is for? Will we ever find out? Do we have hidden in our DNA, ancient memories? Maybe one day we will find out.
