Climate change led to extinction of other human speciesDate: 17 October 2020 Tags: Miscellaneous
According to a latest study, climate change where the temperatures drastically increased or cooled down could have led to the extinction of other human species.
Of the six or more different species of early humans, all belonging to the genus Homo, only Homo sapiens have managed to survive.
The team created the climate changes in those times and studied the fossils of the extinct species.
They come to the conclusion that despite technological advances and revolutionary inventions, the early humans just could not cope with the climate.
They studied the temperature, rainfall, and other data over the last five million years to see how did the different Homo species like H. habilis, H. ergaster, H. erectus, H. heidelbergensis, H. neanderthalensis, and H. sapiens deal with the changes. This was matched with the archaeological fossil database.
According to the researcher, the ancient beings did try to adapt and survive by moving to the warmest places they could find as the climate got cold but their efforts fell short.
It revealed that three Homo species, the H. erectus, H. heidelbergensis, and H. neanderthalensis had lost a significant portion of their climatic niche just before going extinct.
Also, the Neanderthals had to compete with H. sapiens for resources, making things even more difficult.
