Nobel Prize winner Svante Pääbo discusses his work in paleogenetics, including sequencing the Neanderthal genome, discovering the Denisovans, and his theories on why Homo sapiens survived while Neanderthals went extinct, attributing it to our larger population size.
A PBS series 'Human' explores the history of humanity and how *Homo sapiens* became the dominant species on Earth, highlighting the existence of multiple human species and the importance of cooperation in our success.
The article discusses the existence of over 20 early human species that coexisted with Homo sapiens, their potential reasons for extinction (climate change, competition, interbreeding), and the current understanding of human evolution.
The article details a study suggesting that rapid shifts in gene regulation, rather than changes in protein-coding genes, likely drove the evolution of human intelligence. Researchers identified two key regulatory "saltations" – sudden changes – unique to humans that impact areas like memory, learning, social behavior, and emotional depth.
New genetic research suggests that humans first developed language around 135,000 years ago, with its widespread social use around 100,000 years ago. This study, using data from 15 genetic studies, indicates that language likely began as a cognitive system before becoming crucial for social communication.
In a recent study by scientists at UC San Francisco, human accelerated regions (HARs) have been identified as crucial to the rapid evolution of human brain complexity, distinguishing us from our closest evolutionary relatives, chimpanzees. These regions, evolving 10 times faster than the typical mammalian rate, enable the formation of intricate neural networks, which support advanced cognitive functions.
A new genomic study suggests that the capacity for human language emerged at least 135,000 years ago, coinciding with the initial geographic divergence of Homo sapiens. This capacity likely transitioned into social use around 100,000 years ago, as indicated by symbolic activities in the archaeological record.
A study by Professor Ella Been and Dr. Omry Barzilai sheds new light on the burial practices of Homo sapiens and Neanderthals in the Levant region during the Middle Paleolithic, revealing both similarities and differences in how these two species treated their dead.
This article discusses the origin and migration of Homo sapiens, the first modern humans. It covers their evolution, the development of language, and their migration out of Africa between 70,000 and 100,000 years ago. It also touches upon the environmental impacts of human migration.
Analysis of dozens of ancient genomes reveals that close encounters between Neanderthals and humans took place in a narrow time window. The high-resolution analysis also allowed the authors to track when certain Neanderthal DNA sequences appeared in the H. sapiens genome and determine whether they were retained.
