A 2022 attempt at creating a sweeping family tree for the human race, and at least three others, reached back 2 million years, long before Homo sapiens are believed to have originated in Africa 200,000 years ago.

A paper published in the journal Archaeological and Anthropological Sciences undertakes a spatial analysis of the faunal remains and lithic tools for the Neanderthal occupation of level F at the Navalmaíllo Rock Shelter site (Pinilla del Valle, Madrid), which is about 76,000 years old.

Bones found on the remote Arctic island of Spitsbergen suggest the ancient marine reptiles known as ichthyosaurs roamed Earth’s oceans for much longer than we thought.

Chia seeds sprouted in trays have experimentally confirmed a mathematical model proposed by computer scientist and polymath Alan Turing decades ago. The model describes how patterns might emerge in desert vegetation, leopard spots and zebra stripes.

It’s easy to see why most folks think of mushrooms as some type of weird plant, popping out from under the soil when it rains and found in the vegetable aisle of the grocery store…

A 13-sided shape known as “the hat” has mathematicians tipping their caps. It’s the first true example of an “einstein,” a single shape that forms a special tiling of a plane: Like bathroom floor tile, it can cover an entire surface with no gaps or overlaps but only with a pattern that never repeats.

Scientists in Australia have unearthed 3.48 billion-year-old rock fragments that may be the earliest evidence of a meteorite crashing into Earth.

Over the years, several theories have been put forward about Stonehenge’s meaning and function. Today, however, archaeologists have a rather clear picture of this monument as a “place for the ancestors,” located within a complex ancient landscape which included several other elements. See the study here.

Scientists at Dartmouth College in the US have studied how octopuses experience reality in a specialist lab…They question the appropriateness of this for a species that has a sophisticated capacity for processing information, rudimentary tool use, complex visual pathways and, not least, the capacity for pain.

A spectacular series of relief paintings on the ceiling of an ancient Egyptian temple depict 12 signs of the zodiac, and you might be surprised to recognize some of them.

In a study at Imperial College London, detailed brain imaging data from 20 healthy volunteers revealed how the potent psychedelic compound DMT (dimethyltryptamine) alters brain function.

Our planet hides its scars well. It’s a shame, actually, as evidence of previous asteroid strikes might help us better plan for the next catastrophic impact. In fact, NASA’s Goddard Space Flight Center chief scientist, James Garvin, thinks we might have been misreading traces of some of the more serious asteroid strikes that have occurred within the past million years

Researchers have recently conducted a study exploring the potential of a non-hallucinogenic version of LSD for treating mood disorders. Their findings, published in Cell Reports, suggest that non-hallucinogenic LSD could have positive effects of mood, while also reducing the need for medical supervision while taking the drug.

Equinoxes occur twice a year, with daylight and darkness being about the same length in both the Southern and Northern Hemispheres. This phenomenon’s name comes from the Latin words “aequus” (equal) and “nox” (night). In 2023, the spring equinox occurs at 5:24 p.m. EDT (21:24 UTC) on March 20. The autumn, or fall, equinox will happen at 2:50 a.m. EDT on Sept. 23, 2023.

Our understanding of their origins and history on the plateau is patchy. DNA sampling from ancient humans has been limited to a thin slice of the southwestern plateau in the Himalayas. Now a study has filled this gap by sequencing the genomes of 89 ancient humans dating back to 5100 BP.

Vestiges of a moon-forming cataclysm could have kick-started plate tectonics on Earth. See research here.
