And researchers estimate that by 2100, most people will have it.
The reptile is an early member of the animal group Ornithodira to which both dinosaurs and pterosaurs belong.
The facial hair may serve a similar function to a lion's mane, scientists believe.
The largest of these prehistoric species was 10 times the length of anchovies living today.
The shape of the structures resemble that of complex carbon molecules known as "fullerenes," which were one of the first nanoparticles discovered by scientists.
Pangolins are missing two genes that alert mammals to invading viruses. Scientists suggests understanding how they tolerate the virus without these genes could pave way for COVID-19 treatments.
Most electrical activity in vertebrates and invertebrates occurs at extremely low frequencies, but the reasons for this have long remained a mystery.
The virus reemerged in France in 2015, five years after the original outbreak was brought under control.
The skeleton is the most complete of a fossil mammal from the Mesozoic era in the regions that once formed the supercontinent Gondwana.
Researchers say the mata mata turtle split into two species during the late Miocene approximately 13 million years ago.
"It is like finding a new fossil of a long-lost ancestor," researcher Chris Petkov said.
Scientists have used 3D scanning to identify the earliest animal with a front, a back, two symmetrical sides and openings at both ends connected to one another by a gut.
Scientists described how some species of toad choose to mate with males of a different species, showing that females can place sexual pressure on another species for the first time.
More than a century ago, Darwin reasoned genera with more species would contain more variation within those species.
The extinct animal may reveal how modern birds survived the asteroid that wiped out large dinosaurs.
"[The discovery] shows that some of the big steps in evolution we thought were restricted to land animals actually first took place in fishes," said researcher John Long.
Facivermis is a rare animal that evolved to become more primitive, loosing its back limbs when they were no longer useful.
Scientists hope the remains will offer new clues about the emergence of photosynthesising green plants.
Symbolism has been an important part of human society since prehistoric times. Scientists show that engravings become more salient, more memorable and easier to reproduce over time.
New research adds weight to the idea that people became less hairy via sexual selection, with results suggesting women with higher levels of disgust prefer clean-shaven men.
Researchers identified digestive tracts in an extinct worm-like creature known as Cloudina.
"Viruses, like all organisms, adapt and evolve," co-author Joel Wertheim told Newsweek.
Oreopithecus bambolii lived in what is now Italy between 8.3 and 6.7 million years ago.
Researchers analyzing the perplexing behavior say it appears to be some form of communication.
Scientists identified more than 40 new species of cichlid fish in Lake Mweru, East
The swarm of male shrimp were killed in a "mass mortality" event during the time of the dinosaurs.
Traditionally, scientists thought Australopithecus' larger brain size meant it was smarter than modern great apes, but new research suggests that assumption is wrong.
New discoveries in Bavaria of an ape with "orangutan arms" but human-like legs has the science community excited about connecting the dots of evolution between great apes and humans.
