How Are Singular Cellular Organisms Related

Every person on this planet has their own hypothesis on how all organisms are related. Some may believe that there is no correlation between any of the organisms and it has always been that way. On the other hand, some believe that all organisms upon this earth have changed drastically, and we finally reached the point that we are at today after billions of years of adaptation. Now the only way to support a hypothesis is with scientific research, which brings me to the point of bringing up my hypothesis. Personally, I believe that over the course of billions of years that life has inhibited this planet, each organism is related in some way or another, some more obvious than others. Earth itself has had its up and downs, but throughout all this time, life has survived. Tragedies have happened here and there, almost completely wiping out all lifeforms, yet here we still are. I believe that all life forms are related in some way and that we all started out as singular cell organisms. After years of evolution, these single cells evolved into something greater, all life forms that we know today. It is because of this common ancestor that has caused most organisms today to be related, some closer than others. Typically, the original organisms upon this planet split into different
coli, and Paramecium are the only ones that stayed of that similar size. However, these mutations did not just bring organisms that are similar in looks or ways of living, they all came in unique ways, such as plants, animals, and so forth. One of the mutations formed caused all forms of plants, each with a different genetic mutation from the next. It could have started off as something as simple as algae, and came to be such things as the maple tree, fungus, and cacti. Each plant different from the next, each of which going through changes throughout the
