I can’t believe it’s over I watched the whole thing fall And I never saw the writing that was on the wall If I’d only knew The days were slipping past That the good things never last That you were crying
Summer turned to winter And the snow it turned to rain And the rain turned into tears upon your face I hardly recognized the girl you are today And, God, I hope it’s not too late Hmmm… It’s not too late ‘Cause you are not alone I’m always there with you And we’ll get lost together ‘Til the light comes pouring through ‘Cause when you feel like you’re done And the darkness has won Babe, you’re not lost When your world’s crashing down And you can’t bear the thought I said, babe, you’re not lost
Life can show no mercy It can tear your soul apart It can make you feel like you’ve gone crazy But you’re not Things have seemed to change There’s one thing that’s still the same In my heart you have remained And we can fly fly fly away
‘Cause you are not alone And I am there with you And we’ll get lost together ‘Til the light comes pouring through ‘Cause when you feel like you’re done And the darkness has won Babe, you’re not lost When the world’s crashing down And you can not bear the cross I said, baby, you’re not lost I said, baby, you’re not lost I said, baby, you’re not lost I said, baby, you’re not lost

I always have way more fun drawing pterosaurs doing non-flying-related things. Although they’ve traditionally been depicted as sprawling and ungainly on the ground, the anatomy of many pterosaurs actually suggests they stood semi-erect (or fully erect in some types) and were competent at walking and even running.
So this is a male Pteranodon sternbergi (sometimes assigned to its own genus and called Geosternbergia sternbergi instead). Pteranodon is probably the most well-known pterosaur — over 1000 specimens have been found — and most of the time when a movie or TV show depicts a pterosaur it’s either a Pteranodon or a weird chimeric mash-up between it and Rhamphorhynchus.
Pteranodon specimens show marked sexual dimorphism, with the large-crested males being about one-and-a-half times bigger than the small-crested females.

What happens inside a pupa stays inside a pupa. Or it used to, anyway. Until recently, when special x-ray imagers were turned on a developing butterfly to elucidate its metamorphosis.
the process of caterpillar-to-butterfly is a messy one. An overfed worm not only has to convert a lot of the stored energy it gathered stuffing its face for a few weeks into new body parts, it does so by essentially dissolving much of its body and reforming. The pupa isn’t so much a dressing room for a beautiful diva as it is a bag to keep all the goopy globs of proto-butterfly from dripping on the ground. Sounds like both butterfly and human puberty involve a mess of bodily fluids and hiding in your room.
That’s what most biology books would have you believe anyway. This new work (written up in great detail by Ed Yong) demonstrates that while there’s still plenty of goop-globbing, quite a few structures remain intact, migrating and growing into adult forms in a more traditional way (like those blue circulation vessels). For the insect nerds in the bunch, this technique doesn’t revolutionize metamorphosis or anything, but it’s a view inside that most of us have never gotten.
And quite a view it is.

This is a great video to share with friends/enemies/confused relatives that might have trouble accepting evolution and how simple it can be to understand.
I’d like to add one thing to this video. Single amoebas, pairs of parents and a few children are used in these evolution illustrations to simplify the concept of evolution, but it’s important to remember that evolution is something that happens to populations, not individuals. The changes within a generation are random. It’s only after those changes have been passed on for several generations that a survival advantage or disadvantage (followed by either more or less individuals carrying the trait) occurs. That’s where evolution happens, it’s not in the change itself. And sometimes even harmful traits can become frequent in a population, like we see in diseases that are prevalent among isolated ethnic groups.
