Coming and going between ancestors is given below.

Explanation:

Many family stories will tell one version of a story, only to find out the truth when you find the actual records. Genealogy is a very important task for any family. It provides a way to connect with the past while building a future. It gives people a sense of where they came from, while also creating a sense of pride.Your genes have come a long way, have passed through trillions of other organisms, and have undergone an insane number of optimal mutations to finally arrive packaged up together in your chromosomes. You are the way you are because of things that happened to that jellyfish, that lizard, that monkey and the way each of them adapted to their environment for billions of years. I read that when we hiccup, it’s a remnant of a prehistoric impulse in fish—when your body does something or feels something, it’s a window into your deep intertwined connection to all of these other species and to the history of life. Going back to the first particle of life, there are over a trillion fathers and father’s fathers that eventually ended with your parents conceiving you. And if any one of those fathers (or mothers) had died before reproducing—if any of the millions of fish in your line had been prematurely eaten, if any of the millions of rodents in your line had been crushed by a falling tree as a baby—you would not exist. Maybe someone similar to you—but not you.
