Theories Of Evidence Of Evolution

Biological diversity, or evolution, is such a controversial topic, whether it be based on someone’s religion, or simply because they don’t know all of the theories that are out there that explain evolution. If you don’t know, evolution is when there are genetic changes made in the next generation (biologos), or for a better definition, it is genetic change in population from one generation to another (anthro). Meaning, that as each parent has offspring, that new generation has changes made genetically. There are countless numbers of evidence out there for evolution, most of them are by Darwin. But, only 4 pieces of evidence, or theories, will be discussed. The first piece of evidence, or theory, is the ancient organism remains. The second

This is one of many of Darwin’s searches that is evidence for evolution. Darwin found fossil remains that looked almost identical to living organisms today. This is a theory of evolution because it may prove that those fossils could have an ancestor with organisms today. If this were to be true, then it does prove that animals and other things are closely related to organisms from hundreds and thousands, and maybe even millions of years ago. This theory is evidence for evolution because it shows how organisms may have formed and how they evolved. (necsi)

The second piece of evidence of evolution is similarities among living organisms. This theory is one of the ones that truly show that evolution could actually be true. Similarities among organisms is exactly that. It’s like the structure of two different organisms that are the same. For example, a deer and a horse's’ bodies are pretty much the same, so that must mean that they have an ancestor in common, so they may have evolutionized from each other. This supports evolution because, as already stated, it shows that they have evolved from an ancestor they have in common.

This includes homologous and analogous structures. Homologous structures is different animals that have the same bones that are similar in structure and or function and seem to be related in a way. Keeping that definition in mind, think about a human, a bat, a penguin, and a whale’s arms (or even fins). Now, think about the bones. They are all the same, and they have the same function, and they are even in the same general area. This supports evolution because it shows that we are all possibly related in a way. Have you ever heard of a vestigial structure? Vestigial structures are basically useless bones or limbs. The most common carrier of vestigial structures is the whale. Whales have hind leg bones which are very useless. This also supports evolution because it shows that we may have evolved into our own species.
