Homo sapiens interbred with Neanderthals as early as 250,000 years ago and may have ultimately bred them out of existence, according to new research

As well as frescoes of Cerberus, the guard dog of the underworld, the tomb was decorated with paintings of marine centaurs.

Researchers have genetically tested the bones and made determinations of gender and family relations

A horse herder in Inner Mongolia, China, in July 2019.

When Did Humans Domesticate Horses? Scientists Find Modern Lineage Has Origins 4,200 Years Ago

A new study suggests people in the Eurasian steppe bred horses around 2200 B.C.E., challenging earlier ideas about the beginnings of horse husbandry

Ancient Celtic Elites Inherited Wealth From Their Mothers' Sides

A genetic analysis of opulent burial mounds in Germany sheds new light on how power passed through family lines

The fern Tmesipteris oblanceolata, which scientists just discovered has the longest known genome of any organism. Ferns are known among scientists for having particularly large genomes.

This Tiny Fern Has the World's Largest Known Genome

The plant's genome has about 50 times as many base pairs as a human's, and its DNA from a single cell would stretch longer than a football field

Color-enhanced transmission electron microscope images of adenovirus, which is a common cause of respiratory illnesses. Researchers identified adenovirus remnants, as well as herpesvirus and HPV, in Neanderthal remains in a new study.

50,000-Year-Old Neanderthal Bones Have Remains of Human Viruses, Scientists Find

The preliminary analysis is a first step in testing the theory that infectious diseases played a role in Neanderthals' extinction

German cockroaches took advantage of human globalization to spread all over the world.

DNA Reveals How German Cockroaches Came to Dominate the World

A new paper looks at the genes of the most common cockroach species, tracing its historical journey alongside humans, from Asia to the Middle East, Europe and beyond

Baobab trees can reach 100 feet tall, and they support entire ecosystems and communities with their large structures and natural resources.

Scientists Uncover the Ancient Origins of Baobab Trees in Genetic Study

The trees originated in Madagascar 21 million years ago but later traveled long distances by way of ocean currents, according to new research

An MRI of a brain of a person with Alzheimer's disease. A new study suggests having two copies of a genetic variant called APOE4 is a cause of the disease, not just a risk factor for it.

Almost All People With Two Copies of This Genetic Variant Develop Signs of Alzheimer's Disease, Study Finds

The research focused on a variant called APOE4 and largely looked at people of European ancestry—risk levels are different for other groups, the authors say

Previous research had found leprosy in modern red squirrels, and genetic analysis suggested the strain was closely related to leprosy found in medieval humans.

Medieval Squirrels and Humans May Have Spread Leprosy Back and Forth

Archaeologists uncovered evidence of leprosy in a medieval red squirrel in England, and DNA evidence revealed the strain was similar to what was circulating in humans at the time

To create mouse-rat "chimeras," researchers injected rat stem cells into mouse embryos that lacked some genes for brain development.
