*In the archaeological spectrography lab, Sam explains to John how humans have 23 chromosomes while Lucy has 24. Indications are that Lucy was a perfect specimen. Superhumanly strong, fast, intelligent, and healthy. She possessed super healing ability and lived virtually disease free. However, earlier archaeological finds had humanoids with 23 chromosomes, suggesting that Lucy’s 24th chromosome may have been synthesized scientifically.
