So when Darwin found evolution, he found animals were variations of one another. Maybe beaks on birds were different than others, but mostly each type of animal were all similar. This destroyed the idea of the immutability of species (that God created each species of animal specifically). But Darwin extrapolated upon this observation and thought, “If animals can evolve like this, maybe one animal evolved into another. Maybe an elephant can evolve into a finch.” The problem is, he did not find proof for this; he only found that animals evolved slightly. But people took this as a scientific law. Even though the discovery of alleles and genes destroyed the argument for it, people still teach it.
In defining words though, microevolution is the theory that natural selection can, over time, take an organism and turn it into a more specialized species of that organism.
Macroevolution is the hypothesis that natural selection can, over eons of time, take an organism and turn it into a completely different kind of organism.
There are a lot of ways people try to explain macroevolution but they’re often hard to buy because they have to not factor in one problem to solve another.
