You've probably thought about how, if your parents' lives had turned out differently, you might not have been born. And what if your grandparents hadn't bumped into each other? What would have happened then? Or maybe your thousandth ancestor wouldn't have made it onto the ship, or wouldn't have ducked out of the fatal swoop coming towards him? Ever since life appeared on Earth, it has been able to copy the information it carries, so that it can survive with new and smaller changes in each generation. Of course, only if it copies its DNA before it dies. Life on Earth evolved billions of years ago, and despite all the odds against it, it was still able to survive. This incredibly unlikely fact is the reason why we are here right now. All the ancestors of all living things today were able to survive long enough in their environment to reproduce, and each individual's offspring were able to do the same, ultimately resulting in all living things today, including you. If one of these individuals no longer has offspring, then its lifeline is broken forever after almost 4 billion years of unbroken existence. This video was voted on Patreon.
