Did individuals and dinosaurs reside at the very same time?
This concern is an quick one to remedy — and it is an unfortunate, but firm, no (with one noteworthy exception). Humans and non-avian dinosaurs never ever shared world Earth collectively. We did not journey them, nor hold them as pets or harness them for domestic labor.
The facts listed here are rather solid. The non-avian dinosaurs died out 66 million decades back, probably when an asteroid struck Earth and the ensuing cataclysm wiped out a large proportion of everyday living on the world. This integrated just about each and every large organism, and most of the small types as effectively.
In the aftermath, one somewhat humble team was equipped to carve out a considerably bigger footprint for alone: the mammals. These were the creatures that would one day guide to us, just after considerably evolutionary progress and most of the sixty-odd million decades separating us from the close-Cretaceous mass extinction.
At some position in the earlier half-dozen million decades, the previous typical ancestor of individuals and chimpanzees and bonobos (our closest evolutionary family members) break up into two teams. 1 of these would guide one day to individuals, passing to start with through any selection of intermediate teams of hominins. Modern-day individuals are at the moment assumed to have appeared close to 300,000 decades back — more than 65 million decades just after the non-avian dinosaurs disappeared.
But, sure, as you could have by now pointed out: Not all the dinosaurs disappeared. Birds descended from some of the couple of dinosaur species to endure the close of the Cretaceous — probably a kind of theropod.
So, in a complex sense, birds are without a doubt dinosaurs, and we are continue to living with them currently. We eat dinosaurs, we hold them as pets, they choose at our snacks when we go to the seaside. But, just as individuals have advanced much from our mammalian ancestors 66 million decades back, birds have also changed noticeably.
In the long run, it is for you to determine: Are you possessing dinosaur for supper tonight, or just hen?
