Can't it be simply convergent evolution?
- rhelz 3y agoAnything is possible, but it would kind of be like finding two pc-clones, both which contained a copy of MS-DOS, and concluding that each was independently programmed. For the kinds of arguments which scientists use to support these claims, see "Altitude adaptation in Tibetans caused by introgression of Denisovan-like DNA" by Emilia Huerta-Sánchez, et al.
- kryptiskt 3y agoIt would be weird to have the same DNA sequence from convergent evolution, since even if evolution converged on exactly the same protein (unlikely as that may be), most amino acids in the sequence can be represented by several different DNA triplets and there is absolutely no reason why it should converge on the same triplets.
