Could the Dinosaurs Have Had a Now-Lost Civilization?

Geoscientist Dirk Schultze-Makuch asks us to be sure why we believe it couldn’t be true. Not as simple as it first appears…

That’s just crazy talk, right? Geoscientist Dirk Schulze-Makuch, author of The Cosmic Zoo (2017), asks us to think again before dismissing it: Let’s imagine for a moment that some civilization went extinct millions of years before hominids even appeared. Although there isn’t a precise definition of “civilization,” we usually associate it with a species capable of altering its physical environment on a regional or even planetary scale. How would we know, millions of years later, that they had been here? All evidence of their technological achievements is almost certain to have disappeared long ago, as persuasively shown by Alan Weisman in his 2007 book, The World Without Us. Cities and large constructions like dams would quickly crumble and return to…

Experts Guess: How Might Humans Change Over the Next 10,000 Years?

So much has changed in the past few thousand years that the past may not be a reliable guide to the future

Evolutionary biologist Nicholas R. Longrich thinks he knows how human beings will change in the next 10,000 years: It’s hard to predict the future. The world will probably change in ways we can’t imagine. But we can make educated guesses. Paradoxically, the best way to predict the future is probably looking back at the past, and assuming past trends will continue going forward. This suggests some surprising things about our future. We will likely live longer and become taller, as well as more lightly built. We’ll probably be less aggressive and more agreeable, but have smaller brains. A bit like a golden retriever, we’ll be friendly and jolly, but maybe not that interesting. At least, that’s one possible future. Nicholas…

Has the Human Sense of Smell Declined in Recent Millennia?

Researchers found that people with “ancestral” genes perceived various odors as more intense

Recently, a group of researchers embarked on an unusual experiment. They screened the genomes of 1,000 Han Chinese people to find genetic variations that were linked to the way participants perceived 10 different scents, including musk and underarm odor. They then repeated the experiment for six odors in an ethnically diverse group of of 364 people to check their results. They reported that people who had “ancestral” versions of the scent recognition genes perceived the odors as more intense: Participants carried different versions of the musk and underarm odor receptor genes, and those genetic variations affected how the person perceived the scents. In combination with previously published results, the researchers find that people with the ancestral versions (the version shared…
