But that purse seems so unnecessary….
Scientists have found the oldest DNA evidence yet of humans’ biological history. But instead of neatly clarifying human evolution, the finding is adding new mysteries.
In a paper in the journal Nature, scientists reported Wednesday that they had retrieved ancient human DNA from a fossil dating back about 400,000 years, shattering the previous record of 100,000 years.
The fossil, a thigh bone found in Spain, had previously seemed to many experts to belong to a forerunner of Neanderthals. But its DNA tells a very different story. It most closely resembles DNA from an enigmatic lineage of humans known as Denisovans. Until now, Denisovans were known only from DNA retrieved from 80,000-year-old remains in Siberia, 4,000 miles east of where the new DNA was found.
A third kind of human, called Denisovans, seems to have coexisted in Asia with Neanderthals and early modern humans. The latter two are known from abundant fossils and artifacts. Denisovans are defined so far only by the DNA from one bone chip and two teeth—but it reveals a new twist to the human story. [image source]
The mismatch between the anatomical and genetic evidence surprised the scientists, who are now rethinking human evolution over the past few hundred thousand years. It is possible, for example, that there are many extinct human populations that scientists have yet to discover. They might have interbred, swapping DNA. Scientists hope that further studies of extremely ancient human DNA will clarify the mystery.
“Right now, we’ve basically generated a big question mark,” said Matthias Meyer, a geneticist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and a co-author of the new study.
Hints at new hidden complexities in the human story came from a 400,000-year-old femur found in a cave in Spain called Sima de los Huesos (“the pit of bones” in Spanish). The scientific team used new methods to extract the ancient DNA from the fossil.
“This would not have been possible even a year ago,” said Juan Luis Arsuaga, a paleoanthropologist at Universidad Complutense de Madrid and a co-author of the paper.
Finding such ancient human DNA was a major advance, said David Reich, a geneticist at Harvard Medical School who was not involved in the research. “That’s an amazing, game-changing thing,” he said.
Since the 1970s, Spanish scientists have brought out a wealth of fossils from the cave dating back hundreds of thousands of years. “The place is very special,” said Dr. Arsuaga, who has found 28 nearly complete skeletons of humans during three decades of excavations.
Based on the anatomy of the fossils, Dr. Arsuaga has argued that they belonged to ancestors of Neanderthals, which lived in western Asia and Europe from about 200,000 to 30,000 years ago.
When Dr. Meyer and his colleagues drilled into the femur, they found ancient human DNA inside, just as they had hoped.
I already posted eighty things about this, but none of my posts included Bill Nye with Yorick or extra pictures and info. So read this one - it’s better.
Holy shoot you guys!!!!!!!

THE CHEER HAS REACHED CRITICAL MASS
"My body, my choice" only makes sense when someone else’s life isn’t at stake.
Fun fact: If my younger sister was in a car accident and desperately needed a blood transfusion to live, and I was the only person on Earth who could donate blood to save her, and even though donating blood is a relatively easy, safe, and quick procedure no one can force me to give blood. Yes, even to save the life of a fully grown person, it would be ILLEGAL to FORCE me to donate blood if I didn’t want to.
See, we have this concept called “bodily autonomy.” It’s this….cultural notion that a person’s control over their own body is above all important and must not be infringed upon.
Like, we can’t even take LIFE SAVING organs from CORPSES unless the person whose corpse it is gave consent before their death. Even corpses get bodily autonomy.
To tell people that they MUST sacrifice their bodily autonomy for 9 months against their will in an incredibly expensive, invasive, difficult process to save what YOU view as another human life (a debatable claim in the early stages of pregnancy when the VAST majority of abortions are performed) is desperately unethical. You can’t even ask people to sacrifice bodily autonomy to give up organs they aren’t using anymore after they have died.
You’re asking people who can become pregnant to accept less bodily autonomy than we grant to dead bodies.
Just keep on thinking that abortion is okay. Just because you want to fuck without consequences.
And here’s the truth of it: You aren’t concerned with protecting a life.
You are only interested in punishing people for having consensual sex that isn’t driven by a need to procreate. The idea that people could just want to have consensual sex with each other and NOT become parents is something that you take PERSONAL OFFENSE to.
This is a sentiment DRIVEN by a desire to control and restrict people’s ability to have consensual sexual relationships without a specific intention to procreate, and that is gross, invasive, and weird.
YOOOO. TIME FOR AN EPIC POKEMON GIVEAWAY.

One Sylveon Super DX plush.
Choice of any English/Japanese/Korean/etc Pokemon TCG booster box(es) under $100.
The two runners up will receive their choice of Fennekin, Froakie, or Chespin plushies and a Sylveon collection box.
- Both reblogs and likes count.
- Follow me for an extra chance at winning. - Absolutely no giveaway blogs. That’s just unfair.

Good luck to all~
Just a reminder to all of yous, this is still going on! Since this kinda died off on my notifications, I figured I’d just give it a boost. :3
I love this little guy. <3
So Wiley here was getting super stressed from the move. He had to be relocated from my living room to my bedroom. But in my room he isn’t up against a wall like he used to be. I found he was always hiding and wouldn’t come out to see me like he used to. On a gut feeling I duct taped some paper together and stuck it to the backside of the tank and all of a sudden he was out and about just like old times. So we had a tiny photo session.
Has anyone else seen this behavior in their betta? How have you guys gone about fixing whatever is stressing them out?
Oh look, it’s a set of memes about my life.
The Most Intense Color of Any Living Thing on Earth
Also known as the marble berry, Pollia condensata is a wild plant that grows in the forests of several African countries. The berries are not edible, but they have an extremely rare property. They produce the most intense color of any living thing on Earth. Even after the berries have been picked from the plant, they stay the same shiny, vibrant, metallic blue color for many decades.
The vast majority of colors in the biological world are produced by pigments—compounds produced by a living organism that selectively absorb certain wavelengths of light, so that they appear to be the color of whichever wavelengths they reflect.
However, the marble berry’s skin has no pigment. The berries produce their vibrant blue color through nanoscale-sized cellulose strands that scatter light as they interact with one another. Thus the fruit’s color is even visible at the cellular level as pictured above.
truer words have never been spoken
I share that headcanon. c:
>implying that Link being a dweeb isn’t actual canon
shit on ur dash that u super disagree with but dont feel like getting involved with bc tumblr just isnt fucking worth it
Oh my god dont get me started
I’ve gotten requests to do Goldfish ornaments but I want to try it first before anyone commissions me. Would anyone be interested in me doing goldfish ornaments?
