Inflammation, long considered a hallmark of aging, may not be a universal human experience, according to a new study from ...

In green areas, human population density and species richness will decrease; in pink areas, human population density will decrease, while species richness will increase. Ma et al., 2024, CC BY-ND.

Other populations have become cloistered thanks to insular cultural or religious practices. As a result, the genetic ...

While most estimates place the current human population at around 8.2 billion, a new study suggests we might be vastly underrepresenting rural areas.

Human populations in Kenya are growing exponentially, but human populations in Japan have slowed, and may even be declining. What pattern do you expect for human population growth in the United ...

Further support that the human population has undergone a major expansion comes from the consistently negative values of Tajima's D (ref. 6) for not only the Y chromosome, but also for ...

Bobcats, extirpated from Ohio by 1855, have returned due to increasing forest cover. Some of the most iconic mammals on Earth are large carnivores: lions, polar bears, tigers, snow leopards and many ...

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 ...

A lost chapter in human evolution has been revealed after an analysis of modern DNA found that we come from not one but two ancestral populations—ones that drifted apart and later reconnected ...

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 ...

While most estimates place the current human population at around 8.2 billion, a new study suggests we might be vastly underrepresenting rural areas. By analyzing 300 rural dam projects across 35 ...

Other populations have become cloistered thanks to insular cultural or religious practices. As a result, the genetic diversity of our species has declined over the past 50 millennia.
