Over nearly half a billion years, Earth's global temperature has changed drastically, driven by carbon dioxide

Science Daily - Paleontology - Thu, 09/19/2024 - 16:47
A new study offers the most detailed glimpse yet into how Earth's surface temperature has changed over the past 485 million years. The data show that Earth has been and can be warmer than today -- but humans and animals cannot adapt fast enough to keep up with human-caused climate change.

Insights into South African population history from 10,000-year-old human DNA

Science Daily - Fossils - Thu, 09/19/2024 - 10:50
Ancient DNA has provided spectacular insights into human history, particularly in Europe and Asia, where researchers have reconstructed the genomes of thousands of people. However, fewer than two dozen ancient genomes have been recovered from southern Africa -- specifically Botswana, South Africa and Zambia -- which has some of the world's earliest evidence of modern humans, with the oldest genomes dating back around 2,000 years.

Explaining dramatic planet-wide changes after world's last 'Snowball Earth' event

Science Daily - Paleontology - Wed, 09/18/2024 - 15:57
Some of the most dramatic climatic events in our planet's history are 'Snowball Earth' events that happened hundreds of millions of years ago, when almost the entire planet was encased in ice up to 0.6 miles thick. New research provides a more complete picture for how the last Snowball Earth event ended, and suggests why it preceded a dramatic expansion of life on Earth, including the emergence of the first animals.
