The scientific evidence, such as it is:
All human genes have been traced back to two ancestors, the first called “Mitochondrial Eve”, the second misnamed “Y-Chromosomal Adam”. The fact that there is one woman and one man who gave their genes to all is established by the evidence, the “scientists” then do backflips to say that there were actually several thousand individuals, even though they can show no evidence of that. They cannot claim more than that with the evidence they have, and even that is a stretch. Those several thousand fictional individuals are invented to allow them to claim that the Bible is false. Being not backed by evidence, they are, scientifically speaking, falsified.
The woman's genes are traced, using rather iffy methods (the dates may be way off), to an ancient time period, the mans genes to a less ancient time period. This causes the scientists to shriek “see, we told you that story of Adam and Eve was false, they lived at different times!” To this I reply NOAH. The Bible lists one time period when there was one woman who was the mother of all women, and two periods where one man was the father of all men, although in the case of Noah, the father of all surviving men. The second, later man's genes would overwright the first mans genes in the genetic record. The women in the ark were all from different mothers, the men, only from one father (plus the father himself present).
Thus the scientific evidence, which is different than “what scientists believe” (which is not science) validates the Bible as speaking literally.
And the only way one species can evolve into another is if it was planned by a planner, which is the whole problem with evolution. In the case of man, it was simply not planned, and did not happen, since what would God do with a half sentient creature, send it halfway to heaven or hell?
To get a new species, you could, as a planner, have one male and one female born with the same mutations, in the same area, and then have them mate with each other. The chance of that happening randomly is too small to even consider. It is a mute point with "human evolution", since it did not happen, animals and plants are another matter.
