quelling chaos since 2352BC
I'm not a biologist, but I am confident in what I say.That's biologically (scientifically) not true, because there are certain groups of species that can not mate together. Not unless there is genetic engineering involved. And this is what's occurring to us according to the Allies of Humanity Briefings (and the experience of my friend, the testimony and recall of hundreds, and my own discussion between a younger woman and myself who's said she's the mother of hybrid children at a UFO conference. with 13 of them).
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospeciessince fossil reproduction cannot be examined.
If we can interbreed with them and have reproductively viable offspring, then we are one species. If we're having sex with them and they get pregnant with offspring that can also make babies... then they're no further away from us genetically than we were to the Neanderthals.
In short: if we can go to bone town with them and make babies that can have babies, they're us.
