Oct. 29, 2020 — Researchers analyzed the genome of the oldest human fossil found in Mongolia to date and show that the 34,000-year-old woman inherited around 25 percent of her DNA from western Eurasians, ...
Oct. 28, 2020 — Most detailed every study into how animals evolve to better suit their environments shows that pterosaurs become more efficient at flying over millions of years before going extinct with the ...
Oct. 28, 2020 — Membraneless compartments -- models for a potential step in the early evolution of cells -- have been shown to persist or form, disappear, and reform in predictable ways through multiple cycles of ...
Oct. 28, 2020 — Chemists studying how life started often focus on biopolymers like peptides and nucleic acids, but modern biopolymers don't form easily without help from living organisms. A possible solution to ...
Oct. 27, 2020 — Living organisms aren't the only things that evolve over time. Cultural practices change, too, and in recent years social scientists have taken a keen interest in understanding this cultural ...
Oct. 27, 2020 — Big tidal ranges some 400 million years ago may have initiated the evolution of bony fish and land vertebrates. This theory is now supported by researchers who, for the first time, have used ...
Oct. 26, 2020 — Love is not the primary reason humans developed music. A new evolutionary theory of the origins of music argues more evidence supports music coming from the need for groups to impress allies and ...
