Today’s humans carry the genes of an ancient, unknown ancestor, left there by hominin species intermingling perhaps a million years ago.
Archaeologists recently discovered 8,000-year-old stone fluted points on the Arabian Peninsula, the same technology developed by Native Americans 13,000 years ago, according to a study published Wednesday in the journal PLOS One.
Rare find includes skin, tendon and excrement of what is thought to be an adult male
Scientists have solved an enduring mystery about Stonehenge, determining the place of origin of many of the megaliths that make up the famed monument in Wiltshire, England, thanks to a core sample that had been kept in the United States for decades.
A team of biologists from Japan and the United States has successfully revived aerobic microbes found in 101.5-million-year-old sediments from the abyssal plain of the South Pacific Gyre, the part of the ocean with the lowest productivity and fewest nutrients available to fuel the marine food web.
The extinct African crocodile species Crocodylus checchiai may be closely related to American crocodile species alive today, according to a study published in Scientific Reports. The findings suggest that crocodiles may have migrated from Africa to America during the Late Miocene epoch (11-5 million years ago).
