One show-stopper is enough, but a veteran origin-of-life researcher acknowledges four paradoxes in origin-of-life research that have never been solved.
American neurons are due to get a workout this day. The taste buds and olfactory neurons will get their exercise first at Independence Day barbecues across the land, then the visual cortex and auditory neurons will max out as the fireworks start after dark. Escorted by the Editors of Science Magazine, Darwin is here in […]
John Muir said we should not pity plants as prisoners to one spot. In their own ways, they travel the world as we humans do. Anyone who has walked through wild dry grass may have been annoyed at how many foxtails get buried in their socks and how hard it is to get them out. […]
Imagine an alien landing on Earth and trying to figure out two groups of people. One group wields spears and arrows and decides that those who interfere with their traditions are enemies to be killed. Another lives in penthouses and universities and explains the behavior of the other group as evolved tendencies from their animal […]
Evolution is not so much a fact of nature that Darwin discovered, as it is a framework for interpreting evidence. Within that framework are many subplots that can be overturned without falsifying the framework. Here are some recent examples: Chicxulub loses impact: We’ve seen the animations of a giant impact wiping out the dinosaurs. The […]
Anyone analyzing a scientific explanation should evaluate whether it explains the phenomenon or explains it away. For instance, to say that bats have sonar because they evolved it provides little in the way of understanding of how or why that happened. Recently, some scientific papers have directly addressed the topic of complex systems in biology. […]
The Pope recently declared that we need to save humanity from self-destructive behaviors, like homosexuality. Can science intrude on questions of human behavior and morals? New Scientist thought so; a blog entry today says the Pope “misuses science to attack homosexuality.” One would think that moral behavior would lie outside the field for […]
Why do humans get hernias and hiccups? Neil Shubin says it’s because of your inner fish. In the Scientific American series on Darwin, the discoverer of Tiktaalik was trying to show how evolutionary theory sheds light on human anatomy. He looked back to fish and amphibians and found insight. “A glimpse inside the […]
