For millions of years, both early and modern, everyone must find their own food and be forced to spend most of their time collecting plants and hunting animals to survive. Then, over the past 12,000 years, our species has changed from hunters and collectors to revolutionary transitions that produce their own food. Despite this, about 74,000 years ago, due to the dramatic changes in the climate, modern people were almost extinct and the population may have been reduced to only about 10,000 adults of childbearing age. Around this time about 70,000 years ago, a small red star floated near our solar system and gravitationally threw the comets and asteroids - letting them scream inward toward our young sun. In March 2018, a team of astronomers from
Complutense University of Madrid from
Cambridge University in Spain and England announced that they have confirmed that some of these comets and asteroids are affected by this close contact.
