I love these kinds of novel studies. Wonderful Saturday morning reading.

Same, was a brilliant read with a coffee and set me thinking for the day. So much added to my list of things I want to understand better!

Aye. Science is our super power, gifted us by evolution! Thankfully we’re in a time were we get to appreciate the marvels of nature.

It’s mind blowing to appreciate how tiny changes between generations playing out over millions of years has such a significant impact on the ‘original animals.’ Imperfection of one form leading to perfection of another.

As some who doesn't know much about dinosaurs I always assumed pterosaurs are ancestors of birds and not theropods. Interesting to learn theropods were the ancestors.

Cooler still, pterosaurs aren’t even dinosaurs!

Flight is interesting because it’s so useful that it evolved at least 4 separate times. Pterosaurs, birds, insects, bats.

If you include gliding or falling with style in your definition of flight, then it evolved even more times. Sugar gliders and flying squirrels for example. Completely unrelated. Both have a similar solution to gliding. Some snakes can glide too!

If you ever live with a parrot long enough, you'll realize they're really little feathered dinosaurs and start to imagine many of their behaviors aren't too far off from their extinct relatives.

I've had a couple for over a half a decade and they surprise me with their intelligence and their behaviors every day. Decided they might be the pet for me after studying birds in the wild for many years before that.

That said, they're also a handful and don't suggest anyone adopt or buy one on a whim. They tend to latch onto one person. In my case, they love my wife more than me, but we're still "bros". That means they stop caring about attention from me as soon as she walks into the room. It's a little annoying, but that's just the way they are with bonding to a mate for life.

Many parrot rescues will let you foster one for a while, just to get an idea if they're the kind of companion you would want long term

Dinosaurian is an underused adjective, I find
