Because you are new I will help you out. There might be a possibility that you can shake off any atheistic naturalism evolution brainwashing that you went though in the public school system, I don't know. First of all scientists can't even agree on what the definition of a species is. Here is the question, has any evolution been observed that produces a new family of organism? If we have 30,000 species of butterflies, that means nothing, they are still butterflies.
Here is how it could have happened and there is no scientific discovery that can disprove it. God could have created a male and a female cat kind of creature, fully whole in one day that had the genes in it to naturally select and creature all the cats in the cat family today. And God could have created a male and female human fully whole in one day who had the genes in them to naturally select to create all the races of humans that we have today.
What you will find is the ToE isnt even a scientific theory, it is just a model and there are competing models out there that dont get looked out just because they arent atheistic and naturalistic in nature. That is the only reason why science chooses the tree model over the orchard model, because it is the naturalistic one, it is because of philosophy, not science. Do your own research if you dare and you will find that the creation model best fits the evidence.
