Please allow me to postulate Genus Homo-species came into being when a couple of Australopithecus hetero zygotes, who had the same type of chromosome rearrangements formed by fusion of the whole long arms of two acrocentric chromosomes, mated together and reproduced viable and fertile offspring with 46 chromosomes. This first generation of Homo habilis then may have likely incestuously bred with each other and reproduced the next subsequent generation of Homo habilis.
Furthermore, please allow me to postulate there being a mark of intelligence left in our genetic code as evident by how the numeric and semantic message of 037 appears in our genetic code. Each codon relates to 3 other particular codons having the same particular type of initial nucleobase and sequential nucleobase subsequently then followed by a different ending nucleobase. Half of these 4 set of codon groups ( whole family codons ) each code for the same particular amino acid. The other half of those 4 set of codon groups ( split codons ) don't code for the same amino acid. So then, in the case of whole family codons, there are 37 amino acid peptide chain nucleons for each relevant nucleobase determinant of how a particular amino acid gets coded. Start codons express 0 at the beginning of 37 Hence, the meaningful numeric and semantic message of 037 gets unambiguously and factually conveyed to us descendants of our cosmic ancestor(s) with our genetic code invented by a superior intelligence beyond that of anybody presently bound to Earth.
