Yesterday, I was searching the Internet for possible answers to why the mythology of the ancient Sumerians was, in one very important respect, different from the mythology of ancient Egypt.
One thing led to another, and I came across something I had never known before: Chromosome 2.
We are told that the DNA of humans and chimps are 98. something % alike; we are not told that the haploid number of chromosomes in the genus Homo is one less than in other primates.
Apparently there was a random "mutation"---and it probably occurred in more than one individual---that caused the fusion of two chromosomes, resulting in the second largest chromosome in the cell structure of hominids.
Some implications of this occurrence are:
1. It gives credence to the "cladogenesis" theory of evolution: "Cladogenesis is the process by which a species splits into two distinct species, rather than one species gradually transforming into another."--Wikipedia
2. An abnormality associated with Chromosome 2 is synesthesia: "a neurological phenomenon in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway." From here:

3. Apply cladogenesis to rampant and legal abortion, and you have another reason it is illegal.
