Leather jackets that are a style statement today (unfortunately!) may have been a trend from the Pleistocene era! Here’s how researchers from @MPIWG found evidence of early humans who wore leather clothes around 100,000 years ago!
The researchers unearthed 62 bones from layers dating from the Pleistocene era that appeared to have been used as tools. Early humans made these specialised bone tools to skin animals and then processed these skins for fur and leather.
Researchers also found broad, rounded end objects called spatulates, ideal for scraping & removing internal connective tissues from leathers & pelts during the hide or fur-working process. A whale tooth was also retrieved, which appeared to have been used to flake stone.
Remains of sand foxes, golden jackals & wildcats were found with the bone tools, plainly displaying marks similar to those left during skinning. There were no signs of the butchery of these #Carnivore species, but merely the cuts required to remove the skin.

Before this, bone needles discovered in Siberia around 40,000 years ago were the earliest evidence for clothing among the Homo family. Scientists conclude that humans began wearing clothing 100,000 years ago since studies showed the #Evolution of cloth-loving lice to this period.
The scientists also found trinkets such as shell beads, which the early humans could have used as ornaments. With the current evidence, it does look like our Pleistocene ancestors found a way to blend practicality with a bit of whimsy.

Opening jars, playing with toys, sneakily escaping from confinements, jetting water to soak people—#octopuses are notorious for such intelligent antics!
Their large brains make them capable of high-order cognitive behaviours, including problem-solving and tool usage.
Now, researchers have come across yet another interesting behaviour among the female octopuses: one which involves throwing objects at males attempting to mate with them!
The teeth of a new species of the hybodont #shark, which belonged to the #Jurassic era, have been discovered for the first time in Jaisalmer, Rajasthan. #Paleontology#Fossil
The fossils were discovered from the Jurassic rocks in the #Jaisalmer region of #Rajasthan. The rocks are between 160 and 168 million years old.
The crushing teeth represent a new species, named by the research team as 'Strophodusjaisalmerensis'.
The genus Strophodus has been identified for the first time in the Indian sub-continent, and is only the third such record from Asia—the other two being from Japan and Thailand.
The #OortCloud—a shell of debris in the farthest reaches of our #SolarSystem—may consist of more #interstellar objects as compared to local bodies from our own system, as per new research.
It was only two years ago that humans discovered Borisov: the first and only interstellar comet to enter our solar system from a completely foreign star system.
But now, the new study suggests such phenomena might not be too rare!
But if so, why have we only ever seen just one interstellar object so far?
According to study authors, that's simply because we don’t have the technology to see the others yet.
Astronomers have discovered an #asteroid that revolves around our Sun faster than all other #spacerocks! Named 2021 PH2, it is approximately 1 km wide.

This newly discovered asteroid completes one orbit around the Sun in just 113 Earth days. This is the shortest orbital period of any #cosmicobject in our solar system except #Mercury, which takes only 88 days!

This asteroid was initially positioned in the main #AsteroidBelt between Mars and Jupiter but got pulled closer to the Sun by the gravitational influence of inner planets.

#ClimateChange impacts all species through extreme weather events, #habitatchange & #resourcescarcity, and the #Walrus is no different. Declining ice has particularly challenged the survival of female and young walruses.
#GlobalWarming has led to a decline in the #SeaIce that walruses use to rest and access clam beds. Therefore, these mammals are being forced to crowd offshore, where clams are scarce, and the risk of stampedes is high!

Studying #biomarkers at various #foodchain levels is necessary to understand the role of sea ice in the #foodweb. Since clams are an essential part of the Walrus diet, the more they flourish, the more food walruses will have. Thus, researchers use walrus tissues as biomarkers.
