Birds Choose Mates with Ornamental Traits

A recurring theme in nature documentaries is that of choosy females selecting brightly colored males. A new study shows that, in monogamous mating systems, male birds may select their lifelong mates in much the same way.

Was the Primordial Soup a Hearty Pre-Protein Stew?

How proteins evolved billions of years ago, when Earth was devoid of life, has stumped many a scientist. A little do-si-do between amino acids and their chemical lookalikes may have done the trick. Evolutionary chemists tried it, and got results by the boatload.

Apes’ Abilities Misunderstood by Decades of Poor Science

New research argues that what we think we know about apes’ social intelligence is based on wishful thinking and flawed science.

New Computational Model of Chemical Building Blocks May Help Explain the Origins of Life

You and Some 'Cavemen' Get a Genetic Checkup

Evolution has weeded out genetic variants associated with diseases for millennia and propagated genetic variants that protect against ailments, a comparative genetics study shows. But that good trend may have recently gone in reverse.

Understanding Caribbean Mammal Extinctions of the Past Spurs Renewed Focus on Conservation

SiobahnCookeCaveFossils.JPG

A Johns Hopkins paleontologist and her collaborative team of scientists report they have clear evidence that the arrival of humans and subsequent human activity throughout the islands of the Caribbean were likely the primary causes of the extinction of native mammal species there. The evidence, they say, highlights the need for urgent human intervention to protect the native mammal species still inhabiting the region.

Evolutionary Arms “Chase”

ScreenShot2017-08-18at5.40.35PM.png

The study analyzed multiple species of Inga, a genus of tropical trees that produces defensive chemicals, and their various insect herbivores. The researchers found that closely-related plants evolved very different defensive traits. Additionally, their analysis revealed that herbivores may drive evolution of plant defenses, but may not show coevolutionary adaptations. Instead, they may ‘chase’ plants based on the herbivore’s own traits at the time they encounter a new host.
