About 40,000 years ago the ancestors of the indigenous people of the Americas split from the rest of the world following the Pleistocene megafauna and then they flourish mightily, evolving in the Americas, from the Lithic stage to the Post-Classic stage, which was brought into an abrupt end about 525 years ago with the infamous mass genocide and cultural extinction caused by Europeans intrusion into the Americas, bringing diseases and colonizing the Americas with warfare, terrorism, extremists radical Christianity and mass massacres. Only some Native American indigenous groups survived that catastrophe, most of them in Mexico, Central America and South America, with Salvadoran indigenous being one of many who have given rise to all modern Native Americans still alive today.
