Feral Cats as Invasive Species

The ranger stood on the dirt road, facing south, and the rest of us, scattered about the parked safari truck, facing north and paying close attention to what she was saying. The sun was slipping quickly below the red sand dunes to our west, and the day’s warm breeze was rapidly changing to a chill…

Super-sniffing elephants

Like Aesop’s fable, rats have another reason to be envious of elephants. Elephants also have significantly more genes that can detect different smells (i.e. olfactory receptor genes) than other super-sniffers like rats and dogs. In fact, compared to 13 other species, African elephants have 1,948 genes related to smell putting them ahead of the previous…

They don’t understand allometry!

I think the engineers are just trying to wind me up, again. Joe Felsenstein tackles a paper published in an applied physics journal that redefines evolution and tries to claim that changes in aircraft design are a good model for evolution. It’s a terrible premise, but also, the execution is awful. But permit me a…

Biology is a hard problem

New genetic disorders pop up all the time — each one represents a child who may face incredible challenges, or even be doomed to death. A child named Bertrand exhibited some serious symptoms — profound developmental disabilities — shortly after he was born, and no one could figure out what was wrong with him. So…

This flower, over many generations, has warped the poor buff-tail sicklebilled hummingbird’s beak into that bizarre curve.

I’m suddenly seeing more to admire in the beautiful octopus.

The anti-evolutionists just never get tired of the second law thermodynamics! The latest bit of silliness comes from Barry Arrington, writing at Uncommon Descent. Here’s the whole post: I hope our materialist friends will help us with this one. As I understand their argument, entropy is not an obstacle to blind watchmaker evolution, because entropy…

In case you hadn’t heard yet, Science magazine is making a play to reach the supermarket checkout aisle and tabloid market, with exciting new covers featuring sexy womanly body parts and leaving out pointless details like their faces. I don’t know, they could have taken it a step further and featured dramatically posed dead sexy…

Check out this flying dinosaur

The discovery of  this non-avian dinosaur, Changyuraptor yangi, that lived 125 million years ago suggests that flight came before birds. The fossil was discovered in the Liaoning Province of northeastern China by Luis Chiappe from the Natural History Museum in Los Angeles, CA. At nearly 4 feet long, it is the largest so-called 4-winged dinosaur discovered. The term “4-winged”…
