Understanding how complex eukaryotic cells emerged from prokaryotic ancestors represents a major challenge in biology. A main point of contention in refining...
The rusty patched bumblebee (Bombus affinis) is an important pollinator in North America and a federally listed endangered species. Putting together its...
Humans whose genetic ancestors lived outside Africa have a small proportion of the genome that traces back to interbreeding events with Neanderthals. To...
The appearance of human eyebrows is not just a matter of grooming but is in the genes. Eyebrow thickness, as any other appearance trait, is highly heritable....
Osteoderms are bony plates found in the skin of vertebrates, mostly commonly in reptiles where they have evolved independently multiple times, suggesting...
The dispersal of anatomically modern Homo sapiens out of Africa and across Eurasia provides a unique opportunity to examine the impacts of genetic selection...
Scientists have constructed and annotated the first reference genome for the sour cherry cultivar Montmorency, a 400-year-old French amarelle selection...
Scientists from the Florida Museum of Natural History and elsewhere have sequenced 391 genes from nearly 2,300 butterfly species, sampled from 90 countries...
Scientists with the Human Pangenome Reference Consortium have released a new high-quality collection of reference human genome sequences that includes...
ATF3, a gene that leads to a taller nose (from top to bottom), may have been the product of natural selection as ancient humans adapted to colder climates...
Application of a novel non-destructive DNA extraction method to a Paleolithic deer tooth pendant from Denisova Cave, Siberia, resulted in the recovery...
Over the past 100 million years, mammals have adapted to nearly every environment on Earth. Scientists with the Zoonomia Project have been cataloging the...
The sled dog Balto has been celebrated in books and movies for his role in delivering desperately needed diphtheria antitoxin to Nome, Alaska, in 1925....
One of the biggest challenges to growing food on Mars is the presence of perchlorate salts, which have been detected in the Martian regolith (soil) and...
Hornets are the largest of the social wasps, and are important regulators of insect populations in their native ranges. These insects are also very successful...
Skates are cartilaginous fish whose body plan features enlarged wing-like pectoral fins, enabling them to thrive in benthic environments. However, the...
In new research, scientists analyzed 23 ancient genomes of woolly mammoths (Mammuthus primigenius), including one of the oldest known specimens at 700,000...
Most people are familiar with South and Central America’s iconic poison dart frogs, especially the golden poison frog (Phyllobates terribilis), that...
