<span>Good Morning!
The specialization of work is as old as the first human groupings, and it was through division by sex. The invention of the wheel dates from at least 2000 years before Christ, and can be extended up to 3,500 years if we take into account the first illustrations of a wheel. The controlled use of fire, in turn, dates back more than a million years, while the development of agriculture is about 10,000 years old. Thus, among the discoveries and inventions pointed out. It is worth noting, however, that the invention of the wheel, while important, would not contribute to such a large population growth.
Agriculture (letter d), gradually improved from 5,000 BC, is the fundamental factor for population growth, which could now settle, rather than live as a nomad.
Hugs!

Answer:
Regardless of its name, the Big Bang theory found widespread acceptance for its unparalleled ability to explain what we see. The balance of light with particles like protons and neutrons during the first 3 minutes, for instance, let early elements form at a rate predicting the current amounts of helium and other light atoms.
"There was a small window in time where it was possible for nuclei to form," said Glennys Farrar, a cosmologist at New York University. "After that, the universe kept expanding and they couldn't find each other, and before [the window] it was too hot."
A cloudy plasma filled the universe for the next 378,000 years, until further cooling let electrons and protons form neutral hydrogen atoms, and the fog cleared. The light emitted during this process, which has since stretched into microwaves, is the earliest known object researchers can study directly. Known as the cosmic microwave background (CMB) radiation, many researchers consider it the strongest evidence for the Big Bang.
