Human skin color ranges in variety from the darkest brown to the lightest hues. An individual's skin pigmentation is the result of genetics, being the product of both of the individual's biological parents' genetic makeup.
Did humans and dinosaurs live during the same time? Dinosaurs died out 64 million years ago (63.7mya) humans started to evolve 4 million years ago and modern humans some 40,000 years ago -so you have 64 million years between thâ¦em/us unless you count birds, then yes. I've been interested in dinosaurs for the past 15 years.
The dinosaurs were around 100 million years ago, which at the current rate [of day lengthening] adds up to 2000 seconds, which is less than an hour.. But while the lengthening of the day adds up, the spin down rate was probably greater in the past, she adds.
