A college student found prehistoric proof of an evolutionary connection between dinosaurs and birds.
In 2009, a team of scientists from the University of Alberta discovered a dinosaur.
Really.

OK, OK, it was just a partial skeleton of a dinosaur. But it was remarkably well-preserved.
It was unearthed in a fossil-rich area known as Dinosaur Provincial Park. This particular specimen's head and arms were missing, so, at the time, the team of paleontologists decided it was less of a priority than some of the other uncovered fossils and shelved it.
A few years later, the team handed it off to undergraduate student Aaron van der Reest to see if there was anything worth exploring further. You know, just in case.

Just minutes into the project, van der Reest made a monumental discovery: well-preserved dinosaur feathers.
The team had discovered the skeleton of an Ornithomimus (Latin for "bird mimic"), a dinosaur that lived over 75 million years ago. The Ornithomimus stood over two meters tall, but more than that, it had fine feathers covering its neck, back, and tail. Its legs, however, were completely bare.

Many scientists believe birds and dinosaurs have a biological connection and this finding is one more piece of prehistoric proof.
To date, scientists have discovered three Ornithomimus skeletons, but the discovery of such well-preserved soft tissue and feathers makes this a rare and exemplary specimen. After years of extensive preparation and additional research, the team (lead by van der Reest) published their analysis of the feathers last week.
The Ornithomimus was a fast-moving, flightless creature. Why did it have feathers?
The paleontologists examined the feathers under an electron microscope and discovered a structure that is very similar to a modern-day ostrich feather.

Like the Ornithomimus, ostriches are fast-moving, can't fly, and have bare legs. They use their feathers as an efficient way to regulate their body temperature. Van der Reest and his team believe that Ornithomimus most likely used its feathers in the same way.
While it's widely acknowledged birds and dinosaurs have an evolutionary connection, this discovery provides proof of an important missing link.
"By knowing that this method [of temperature regulation] was being used so early in the origins of birds we can get important insight into the evolution of temperature control in large ground-dwelling birds like ostriches and emus," van der Reest told the Huffington Post.

Birds are thought to have descended from carnivorous predators like Archaeopteryx, and Hesperornis, due to their bone shape and egg features. But this breakthrough suggests there may be a common ancestor at the top of the avian family tree.
Hats off to van der Reest for turning a seemingly ordinary undergraduate project into a seriously awesome dino-discovery!
There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
