Mother, father, grandmother, grandfather and their countless grandparents… Have you ever thought how far this cycle goes? Or if our lineage goes back so far and each of us has a connection with each other, is there a possibility that we are related?
“Can something like this really happen?” We seem to hear you say. At the same time, we can easily say that you have not thought much about this issue before.
Well seriously actually Can each of us be related to each other?
When we think of it in its simplest form; We have two parents, four grandparents, and eight grandparents along with theirs.
Four generations ago, our ancestors were thirty people in total. If we continue with this logic and double each step, just forty generations ago, We have almost a trillion ancestors living at the same time. we can find it.
Although it sounds a little meaningless, this number is actually There have never been more people alive. Since our species emerged two hundred thousand years ago, perhaps seven or eight thousand generations have been born and passed away.
At this point, when we think about where our lost ancestors are, we can clearly conclude that there was inbreeding.
Because so many people with common ancestors have bred, the number of our actual ancestors is essentially much less than the mathematics tells us. But every person alive today share a common ancestor in the family tree and in fact this person lived only three thousand years ago.
On the other hand, each of us carries the record of our ancestors in our genes, but DNA Since it has been copied many times, some errors occur from time to time, so to speak. occur and differences arise.
However, since our DNA can be changed without affecting most functions, Most of these mutations are passed on to the next generation. These genetic changes accumulate over time, so scientists can estimate how much time has passed by reading them like a molecular clock.
In addition, the changes individuals have tell us how close or distant relatives they are to us.
Although a Chinese and a Turk seem quite different, they are actually Our DNA levels are quite similar. Even a group of chimpanzees living in central Africa has much more genetic diversity than one finds in the entire human population.
It may not always be clear where we come from, or in other words, where we are from, but DNA is infallible. We all have a single ancestor who lived thousands of years ago, but these genetics are so mixed up that It is not possible for us to see its traces in our DNA.
In summary, each of us We are truly relatives, even a very large family. However, our ancestors are not only branches extending to the past, but also a tree extending to the future.
