Ethiopian fossils reveal new species in human evolutionary lineage

Researchers have unearthed tooth fossils in Ethiopia dating to about 2.65 million years ago of a previously unknown species in the human evolutionary lineage, one that lived in the same time and place as the earliest-known member of the genus Homo to which our own species belongs. The scientists discovered in the Ledi-Geraru research project area of northeastern Ethiopia's Afar Region 10 teeth - six molars, two incisors, one premolar and one canine - that they concluded belonged to a new Austra...

Fossil study finds how sea level changes shaped early life on Earth

A groundbreaking study from the University of Edinburgh has unveiled a new timeline of early animal fossils, suggesting a significant relationship between sea level fluctuations, marine oxygen variations, and the emergence of the earliest ancestors of present-day animals. The research, focusing on the Ediacaran-Cambrian interval (580-510 million years ago), provides fresh insights into the processes driving the development of Earth's earliest creatures. This period, long known for its explosion...
