No sir you are incorrect it is merely a guess at best....... a circular argument pointing to homologies through the genome... (and I am not even addressing “junk DNA”)...... THERE ARE NO HALF-BATS...........
We know where genes come from. Genes are expressed as physical features. We know what the genes are for chimps and for humans. We know that prior to a particular speciation event, our genomes were the same. In other words, our physical bodies were the same. We were once a single species.
