species of them own, most likely due to mutations. The more mutations made, the more unique species emerged. It is because of these years of mutations, that caused such a large amount of species to be introduced into this world, some surviving, and some not.
Since mutations were forming new species, most of these singular cell organisms evolved into something bigger, but it seems that E.
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
years.
On the other hand, there are numerous different animals that came out as diverse mutations. Some animals are more closely related together than others. For example, some reptiles such as alligators, snakes, and frogs are more a like each other than they are to insects such as a praying mantis, a land snail, and a wasp. Even within the whole mammal department, there are still some mammals that are extremely different but still distantly related. Bison, cats, and macaque are all mammals along with birds like a bat and a pigeon, but they are still very different in nature. The same thing applies to marine animals, such as the whale, bass, and marine worm when comparing them to each other. One of the most controversial relations between animals would have to be through the chimpanzee and the Homo sapiens. In my personal opinion, Homo sapiens have evolved from something similar to chimpanzees. Either way, all organisms have drastically changed since the first organisms on this planet.
Each and every species has been evolved and mutated into something different, causing the broad range of species that we have today. Life started billions of years ago, right after the world itself was created, and it has evolved and adapted into something beautiful that we see every day. Change was a good thing, and the mutations and modifications created all the species that are well known in the current age, along with others who have already become extinct. Either way, life still persisted to evolve into the remaining life forms that still roam this earth to this day. All of which becoming stronger every day, and surviving everything that comes their way.
