Why Are There No Elephants In North America?

Why Are There No Elephants In North America? Today, there are no elephants living in North America. They are currently only found in Africa and Asia but they did once roam America. So, what happened to them and how did they get to North America in the first place? If we could travel back millions of years, then we would see the development and evolution of the proboscideans or elephant-related animals. These developed in a world with a significantly different climate and geography from today. The proboscideans were incredibly adaptable and evolved along with the transformation of the planet. Elephant evolution began some 50 or 60 million years ago. The first creature was a small pig-sized herbivore with a long flexible nose. With the appearance of open landscapes, came significant evolution of the elephants’ ancestors. Changes in atmospheric gases led to changes in vegetation and grasses. In turn, the dentition of many herbivores, including early elephant-like species, evolved to enable the animals to consume these plants. About 3.2 million years ago, there was a big dispersal of elephant-like ancestors from Africa. Mammoths traveled to northern Eurasia and Elephas planifrons traveled to the Indian subcontinent. 2.6 million years ago, glaciation occurred in the northern continents and sea levels dropped. This enabled animals to cross intercontinentally between Europe and North America. The mammoths migrated from Europe to North America around this time. ➽Consider to subscribe:    / @factsmachine   ➽Audio: www.bensound.com, YouTube Audio Library ➽Contact: factsmachine.ro@gmail.com #elephant #america #wildlife
