Yes, that explains why people who lived in the early agricultural societies, who had easy lives, also had a lot of children. It explains why, today, those with the highest birthrate end up becoming the majority, consistent with the principles of natural selection.
You need to realize something about natural selection -- the future population belongs to those with the highest birth rate, whoever and wherever they are. You should know this, but you clearly do not.
In Israel, arabs are outbreeding Jews and will eventually become an absolute majority:

In the U.S., groups other than White descendants of Europeans are outbreeding them and will soon become an absolute majority, as they already are in California:

I'm not complaining about the ethnic makeup of the future, I'm only making the point that natural selection blindly chooses those with the highest birthrate, and it is that group that becomes the future population of the world.

It is you who needs to educate yourself on this issue. You posted opinions, I posted facts. You haven't the slightest idea what you're talking about.

Quote: "As of September 10, 2013 the world's human population is estimated to be 7.11 billion by the United States Census Bureau, and over 7 billion by the United Nations. Most contemporary estimates for the carrying capacity of the Earth under existing conditions are between 4 billion and 16 billion. Depending on which estimate is used, human overpopulation may or may not have already occurred. Nevertheless, the rapid recent increase in human population is causing some concern. The population is expected to reach between 8 and 10.5 billion between the year 2040 and 2050. In May 2011, the United Nations increased the medium variant projections to 9.3 billion for 2050 and 10.1 billion for 2100."
