Homo sapiens, the ancestors of modern man, originated in Africa.

The “Out of Africa” theory suggests that our ancestors left the continent and migrated to Europe and Asia. In doing so, they began replacing earlier examples of the human species - the Homo Erectus.

This migration took place approximately 80,000 years ago. What is interesting to note is that the Homo erectus (upright human) had actually followed the exact same route (from Africa to Eurasia) - over 1 million years ago.

Many anthropologists now believe that early humans probably did not develop a culture until around that time. When we consider that the "mitochondrial Eve" theory suggests that we are all descended from one East African woman who lived about 200-150,000 years ago, It is shocking.

Homo sapiens has only had a culture for less than 50,000 years

Homo sapiens evolved over 150,000 years ago, around the time of mitochondrial Eve - the most recent common maternal ancestor of people currently on Earth.

Early Humans have incredibly low genetic diversity

Humans are among the least genetically diverse species, mostly because we probably descended from a small group of early humans who lived in East Africa.

Population geneticists describe genetic diversity with a measure called "effective population size." Basically, effective population size is how many people you would need to reproduce the genetic diversity of our full population.

For humans, this number is really low and hovers around 15,000 individuals. It is kind of crazy when you consider that actual population size is 7 billion. If compared to mice, some species of them have an effective population size of 733,000.

About 80,000 years ago there was a drastic reduction in the size of the human population.

Archeologists are still not 100% sure what caused the decline, but it definitely wasn't pretty.

Some say there may have been a massive volcanic eruption that filled the sky with millions of particles of ash, blocking the sun’s heat for many years and in so doing created freezing temperatures that would have severely affected life and population growth on earth at the time.

“In prehistoric times, Homo sapiens was deeply endangered. Early humans were less fleet of foot, with fewer natural weapons and less well-honed senses than all the predators that threatened them.

The more that is uncovered from the past, the more we learn about how similar modern humans are to our prehistoric ancestors.

From medicinal practices to tattoos to the DNA, even though technology has vastly changed, not much about who we are has. Covering a wide range of different Homo genus groups, prehistoric humans were able to survive through the toughest of times, yet only Homo sapiens were able to make it to modern day. Good job guys!

Prehistoric humans didn’t actually discover fire—instead, it was our previous hominid relatives that likely figured out how to produce a controlled flame.

As the first hominid to walk upright and use tools, evidence suggests that Home erectus was also the first to claim the coveted title of “master of fire.” The earliest unearthed fire pits have been found in Africa and date back to around two million years old.

The recent African origin of modern humans is the mainstream model describing the origin and dispersal of anatomically modern humans

Venus in the Ground
Dating back roughly 30,000 years ago, the Venus of Willendorf is one of the first cultural items found during the Paleolithic period.

The hypothesis that humans have a single origin was published in Charles Darwin's The Descent of Man (1871).

Many other Venus figurines (ancient statuettes portraying a female body) have also been found, and they are believed to have been used as symbolic fertility totems of a mother goddess.

The concept is supported by a study of present-day mitochondrial DNA, and with evidence based on physical anthropology of fossil humans.
