But this wasn’t a bird-like we know them today. It’s got wings, feathers, and an overall bird-shaped body. It’s been nicknamed the “first bird,” since it’s among the earliest known fossil animals with obvious bird features. Archaeopteryx was discovered in the 1860s in 150-million-year-old rocks from the Late. Let’s start at the beginning, with the most famous weird bird of all time: Archaeopteryx. So here are some extinct examples whose strange features might make you rethink what you know about evolution - and maybe how you define birds altogether. Because when evolution gets the chance to riff on the basic bird plan… it takes it. But birds have been around for a good 150 million years, and in that time, they’ve come in all sorts of forms, not all of which are familiar to us today. Beaks, feathers, wings, screams for peanuts way too early in the morning. This episode is brought to you by the Music for Scientists album, now available on all streaming services.

They also tend to be happier and feel healthier than night owls, according to a recent study from the University of Toronto.This episode is brought to you by the Music for Scientists album!

Morning people, however, also have advantages. A recent study in Belgium found that night owls are able to stay more focused as the day goes on, compared with early risers. "There's a developmental piece to this puzzle - school-age children are generally early birds, while teenagers tend to be night owls, and then as they age, adults gradually transition back into morning people," Sharkey says.īesides the obvious problems with being a night owl if you have a day job, "night owls tend to be more depressed, have a higher dependence on caffeine, and use alcohol more," Sharkey says. If it runs short, you're probably an early riser.īut your circadian rhythm can change over your lifetime. "But some people have a slightly longer natural cycle, and some are slightly shorter." If your circadian rhythm is on the long side, you're more likely to be a night owl. "The human clock is about 24 hours, thanks to Earth's 24-hour light-dark cycle," Sharkey says. The question is: Why? The answer lies in each individual's biological internal clock - or circadian rhythm, as scientists call it. "More women tend to be larks, while men lean toward being night owls," she says. The couple learned to work around their differences over the years, but their situation is not uncommon, says Katherine Sharkey, MD, PhD, assistant professor of internal medicine and psychiatry and human behavior at Brown University and associate director of the Sleep for Science Research Lab. "We ended up getting into a lot of arguments because I took his shrugs to be disinterest, when really he was just still half-asleep."
"When we were planning our wedding, I wanted to have these big discussions at 8 a.m., when I had been up for two hours and was fresh, but Jim would just be getting out of bed," says the 46-year-old floral designer from Melrose, Mass.
Early in their relationship, it posed quite a problem.
