Question

Who was the first human?

Answer 1

Since our predecessors traded DNA, the tale of human origins is convoluted (and probably skills). Long before modern humans known as Homo sapiens evolved on the same continent, the first humans appeared in Africa some two million years ago. There's still a lot anthropologists don't know about how different groups of humans interacted and mated over such a long period of time.

Complete answer:
First and foremost: Any member of the species Homo (Latin for "man") is referred to as a "human". Scientists are still unsure when or how the first humans emerged, but they have identified some of the earliest.
Homo habilis , or "handyman," was one of the oldest known humans, living between 2.4 million and 1.4 million years ago in Eastern and Southern Africa. Others include Homo rudolfensis , who lived in Eastern Africa between 1.9 million and 1.8 million years ago (its name comes from its discovery in East Rudolph, Kenya); and Homo erectus, the "upright man," who lived from about 1.89 million to 110,000 years ago and ranged from Southern Africa to modern-day China and Indonesia.
In addition to these early humans, scientists have discovered evidence of a mysterious "superarchaic" tribe that split from the rest of humanity some two million years ago in Africa. According to a report published in Science Advances in February 2020, these superarchaic humans mated with the descendants of Neanderthals and Denisovans. This is the oldest known case of human groups mating with one another, though we know it happened a lot more afterwards.
Following the superarchaic humans came the archaic humans: Neanderthals, Denisovans, and other extinct human species. Neanderthals, or Homo neanderthalensis , have been known to archaeologists since the 19th century, while Denisovans were only discovered in 2008 (the group is so new that it lacks a scientific name). Since then, researchers have learned that Neanderthals and Denisovans mated with modern humans as well as each other.

Note:-
A catastrophic asteroid attack 65 million years ago wiped out not only the dinosaurs, but virtually any animal weighing more than 25 kilogrammes (excepting leatherback sea turtles and some crocodiles). This was the most recent great mass extinction on Earth, and it left a lot of empty niches in its wake. In the aftermath, mammals rose to dominance, with the first humans appearing fewer than 1 million years ago.
