Neanderthals may have been morning people, says new study

A new research paper finds that genetic material from Neanderthal ancestors may have contributed to the propensity of some people today to be "early risers," the sort of people who are more comfortable getting up and going ...

Explainer: What is the molecular clock?

In the 150 years since Charles Darwin recognised the kinship of all life, scientists have worked to fulfil his dream of a complete Tree of Life. Today, the methods used to trace the evolutionary branches back through time ...

Oldest existing lizard-like fossil hints at scaly origins

The fossilised remains of a reptile closely related to lizards are the oldest yet to be discovered. Two new fossil jaws discovered in Vellberg, Germany provide the first direct evidence that the ancestors of lizards, snakes ...

How molecular clocks are refining human evolution's timeline

DNA holds the story of our ancestry – how we're related to the familiar faces at family reunions as well as more ancient affairs: how we're related to our closest nonhuman relatives, chimpanzees; how Homo sapiens mated ...

Plants use circadian rhythms to prepare for battle with insects

In a study of the molecular underpinnings of plants' pest resistance, Rice University biologists have shown that plants both anticipate daytime raids by hungry insects and make sophisticated preparations to fend them off.

Researchers synchronize blinking 'genetic clocks' (w/ Video)

Researchers at UC San Diego who last year genetically engineered bacteria to keep track of time by turning on and off fluorescent proteins within their cells have taken another step toward the construction of a programmable ...

Newly discovered molecule essential to resetting 'body clocks'

(PhysOrg.com) -- Research has shown that light is the key to getting our 'body clocks' back in sync and now a new study exploring the resynchronisation mechanism in insects has discovered a molecule essential to the process.
