Either climate change, or competition from Cro-Magnon man (modern humans), or a combination of both.
Scientists propose that the Neanderthals were stocky and likely to be forest dwellers, getting food and shelter from the dense forests of Europe. As the climate changed and forests receded the taller, leaner modern humans were better able to cope. The last Neanderthals probably lived around southern Spain.
There is genetic evidence that modern humans and Neanderthals interbred. This means that all humans apart from those of recent African ancestry have some Neanderthal genes. Africans do not as their ancestors did not leave Africa.
Hurricanes because it covers the most land.
Extinction events, such as the Permian extinction and the KT extinction event. You have adaptive radiation driving evolutionary change after such events. Google " the rise of the mammals. "
Deforestation, because most of animal species live in the rainforest but it is getting cut down so animals get closer to extinction. Like the jaguar.
Most likely from H. heidelbergensis.
Extinction
most probably change in the climatic condition was the main reason for their extinction!!
Human
Blue-fin tuna fish are really close to extinction. They are most likely have the Highest Chances Of Extinction!

Deforestation of rainforests will likely lead to extensive extinction of species.
Change of climate,potchars,and other animals eating them.
