Coelacanth: Making the Most of an Unevolved Fish

The coelacanth genome has been sequenced. Does it show evidence for evolution? Only to those with a good imagination.

Wood You Cellulose for Starch?

Cellulose is the most abundant biomolecule, but how it's made still baffles scientists. Soon, though, you may be able to eat it.

Human and Animal Brains: Uniquenesses and Similarities

Several recent science articles explore what we have in common with animals, and what is unique about the human brain.

The Hunt for Selection in the Genes

One might think that 154 years after Darwin's book about it, natural selection would be empirically obvious. The journal Nature went on a search for it in DNA.

Laughing Matters

Why is it that scientists need to investigate "the evolutionary origins" of anything humans do?

Of Hagfish, Geckos and Dragonflies

Some of the most unlikely creatures are making headlines because of their potential for advancing technology.

Before the Cock Crows, the Biological Clock Strikes

At Easter time, people recall the story of Peter denying Jesus three times before the rooster crowed. Some scientists tried to figure out what clicks the rooster's clock alarm.

Freckled Trilobites Had Great Eyes

Darlings of the Cambrian Explosion, trilobites had spotted markings and sophisticated eyes. Some have been exceptionally well preserved as fossils, down to the level of individual cells.

Scientific Findings Can Be Counterintuitive

Here are examples of recent claims in science that seem to contradict what some would consider intuitively obvious. They should be kept in mind when evaluating other scientific truisms, like evolution.

Biomimetics Matching Game

Try your hand at matching the organism with the new technology being developed from its design.

The Ediacaran Era May Be a Flawed Concept

Before humans arrived, no strata came with "Ediacaran" stamped on them. Does this human-invented name have any real meaning? Does it tell time?

Evolution Is Not Just Change or Similarity

Many scientific findings get labeled with "evolution" even though neo-Darwinism has nothing to do with them.

Arctic Camel Found

Fossils from a large species of camel living in Canada's high arctic contain soft tissue.

This "Evolution" Is Not Darwinian

Some things in nature get attributed to Darwinian evolution, but might be better seen as manifestations of design or other alternative, non-Darwinian mechanisms.

Intact Biomolecules Claimed to Be 350 Million Years Old

The oldest recovered biomolecules have been found in crinoid fossils – but are they really that old?
