Why did early humans migrate out of Africa?
In a study published today in Nature, researchers report that dramatic climate fluctuations created favorable environmental conditions that triggered periodic waves of human migration out of Africa every 20,000 years or so, beginning just over 100,000 years ago.
Why did Hominins leave Africa?
Possibly, but other scholars point to more mundane factors that may have contributed to the exodus from Africa. A recent DNA study suggests that massive droughts before the great migration split Africa’s modern human population into small, isolated groups and may have even threatened their extinction.

Are 8th cousins blood related?
You’re an 8th cousin of anyone with whom your closest shared ancestor is a 7g-grandparent of one of you. In this case you’re twice removed because your relationship is 2 generations farther removed than Loretta’s. And then you would have up to 2**9 more 9g-grandparents to analyze for similar results.
How many descendants will I have in 100 years?
It is not uncommon for some to find five generations in the past 100 years, although four will be an average for this example. Conversely, your future generations will wait longer to have children; therefore, expect only three generations in the next 100 years.
Are 11th cousins blood related?
No, not at the 11th cousin degree is everyone related. A great many people are 11th cousin or closer to you, but not all. Many of these, if not most of them, are related to you in more than one way. Those are people who have a common ancestor with you where the common ancestor was living about 500 years ago.
