Monkey Raspberries Created Speech

What was this evolutionist thinking when he proposed that human language evolved out of the lip smacking and buzzing sounds made by monkeys?

Spiders Can Cross Oceans

Why did the spider cross the ocean? To colonize the Old World after it "originated" in the New World.

Ready, Aim, Flower

How does a plant know the time to flower? A new study describes a process involving genes, sunlight sensors, switches, clocks, feedback loops and messages.

Written in Ink: No Evolution

An ink sac from a fossilized Jurassic cephalopod said to be 160 million years old looks identical to those from living cuttlefish.

Animal Sin: What Does It Imply?

Some animals commit cruel or disgusting acts humans would consider immoral. What does this mean?

Beak Careful: Variation May Be Non-Darwinian

Finch beaks loom large in classical Darwinian theory, but two examples of mouth parts in very different animals show that dramatic variations can be achieved quickly without the slow and gradual accumulation of small changes Darwin envisaged.

Butterfly Mimics Don't Evolve; They Share

A non-evolutionary explanation has been found for a classic evolutionary showpiece: mimicry in butterflies.

Improbable Ape Speaks Randomly

It's not uncharitable to call someone an ape when he calls himself that.

From Toxin to Medicine

Botulinum toxin (botox) is now big business in health and fashion, but few may remember it derives from one of the deadliest substances known in nature. Other examples show that some forms of "natural evil" can be seen in a different light.

Evolution for Men and Women

Two recent entries in the evolution literature have application to one sex or the other.

Follow the Leader: Plants and Animals

Need solutions to engineering problems? Look no further than the plants and animals around you. That's what more and more scientists are doing.

Coelacanth: Survival of the Dullest

A new fossil species of coelacanth was discovered in Canada. Scientists think from its tail fin shape that it was a fast swimmer–perhaps a hunter. Sadly, it was a "spectacular failure" in evolution. The luck of the evolutionary draw went to today's slow-moving, docile species.

Animals Have Biological GPS

Global Positioning System (GPS): that's a function. Maintaining a suite of satellites is one method for achieving the function. But there are other ways to figure out where in the world you are, and two very different animals show the way – naturally – using Earth's global magnetic field.

How the Tiger Got Its Stripes: Dunno

A leading hypothesis for morphogenesis (pattern formation, such as tiger stripes) has been shown to be oversimplified. Whatever gave a tiger its stripes is more complicated than developmental biologists thought.

Questioning the Dino-Bird Hypothesis

The scientific consensus has pretty much declared it a fact of natural history that birds evolved from dinosaurs. One evolutionary professor remains a gadfly, though. He contests the evidence on which the hypothesis is based, and also believes his maverick position is growing.
