When evolution goes haywire: 5 examples of maladaptation in the animal kingdom

Many people perceive evolution as a process that continually creates improvement, making animals ever bigger, faster and stronger. However this is not always the case. During sexual reproduction random genetic mutations can occur—some of these mutations cause changes that adapt the animal for optimal survival in its environment. Some changes may be neutral, but some … Continued

Just how big can animals grow?

From fish that fly and lizards that squirt blood from their eyes, to insects that wear dead ants as a disguise. Welcome to the weird world of unusual defense mechanisms. … Continued

Cities: Evolutionary hot-spots for wildlife

In fact, his research sometimes takes him just as far as his backyard. ‘Our field sites are literally right outside our homes and universities,’ he explains, ‘I can squeeze in some trapping or other sampling in a city … Continued

The last unicorn

The skull of a mighty unicorn has just been discovered in Kazakhstan, which has forced scientists to rethink longheld theories about the survival of an extraordinary species, to look again at where it walked the Earth, and reassess how long it could have survived in some regions of the globe.

Eat your greens! The secrets to how herbivores grow so large

The largest land animal that ever lived was a vegetarian. When a local farmer stumbled upon a thighbone in Patagonia, he initially assumed it was a gigantic segment of petrified wood. But as paleontologists from around the world began to excavate, they found the fossilised remains of perhaps the largest animal species ever to walk … Continued

Did our tooth enamel evolve from fish scales?

Researchers cut up a 415 million year old fish fossil searching for the origin of the hardest-vertebrate tissue out there Sometimes evolutionary concepts can be hard to come to terms with. Take for example, the fact that land vertebrates arose from fish. This isn’t new information, but there’s a lot about this linkage that remains unknown, … Continued

How have sharks survived for 400 million years?

Sharks roamed the seas over 400 million years ago, before the dinosaurs. They’ve survived 5 mass extinctions and evolved into a perfect predator. So what has made them so successful?
