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.
Geological timescale. Triassic period: 250â200 million years ago. Jurassic period: 200â145 million years ago. Cretaceous period: 145â65 million years ago. Dinosaurs roamed the planet for about 165 million years, during a time in the Earthâs history called the Mesozoic Era. It is difficult to imagine how long this was, until we compare it with ourselves: humans have lived on Earth for less than two million years. During the Mesozoic Era, the Earthâs landmasses changed dramatically, new seas were formed, and plants and animals evolved.
