Clearly human population now far exceeds its expected share of the ecological system, as one among many animal species. My interpretation of Dilworth’s theory applied to humans Primitive Societies .

In the early 1800s, the human population hit 1 billion. As of late last year, human population 8 billion. And by the end of the century, it’s expected to top ten billion. What does that mean for ...

If the human population continues to grow, more pressure will be put on carbon dioxide emissions — leaving future generations vulnerable to the effects of climate change. To head this off, greenhouse ...

Between the year 1 and 1700, the human population went from about 200 million to about 600 million; by 1800, it had barely hit one billion. Then, the population exploded, first in the United Kingdom ...

Global Human Population Isn't Going to Explode—But That Doesn't Mean We're Safe | Opinion. Published Sep 26, 2018 at 8:58 AM EDT Updated Sep 26, 2018 at 9:34 AM EDT.

Human Population Growth and extinction. We're in the midst of the Earth’s sixth mass extinction crisis. Harvard biologist E. O. Wilson estimated that 30,000 species per year (or three species per hour ...

Human population numbers did not reach high levels until after the advent of agriculture. Geneticists have long known that the ancestors of modern humans numbered as few as 10,000 at some time in ...

That means that indirectly at least, the mass of the human population comes from the air. When people die, they decompose and produce more carbon dioxide. It’s an endless cycle.

Neanderthals may not have truly gone extinct but instead may have been absorbed into the modern human population. That's one of the implications of a new study, which finds modern human DNA may ...

The population of early humans dwindled to around 1,280 individuals during a time of dramatic climate change and remained that small for about 117,000 years, the study said.

An ‘ancestral bottleneck’ took out nearly 99 percent of the human population 800,000 years ago. Only 1,280 breeding individuals may have existed at this dramatic era of human history.
