    Conservationists should make friends with hunters

    For the sake of wildlife conservation everywhere, birdwatchers and other animal lovers should join forces with hunters.

    Fans of wildlife are going to read that and think I’m crazy. But if we want more allies in efforts to protect wildlife, we should look to hunters.

    Responsible hunters, on the other hand, will read this and think, “well of course we want to protect wildlife.” If...

    Ancient wolf skulls challenge dog domestication timeline

    When did dogs become our best friends? Recent studies pushed canine domestication back to the late Pleistocene epoch, when humans still lived as hunter-gatherers. However, a 3-D analysis published February 5 in Scientific Reports suggests...

    Snakes crawled among Jurassic dinosaurs, new timeline says

    Just call it the Jura-sssss-ic Period. Newly identified fossils suggest that snakes slithered through much of the golden age of the dinosaurs, a finding that pushes back the fossil record for snakes by 70 million years.

    Ancient skulls with features similar to modern snakes tipped paleontologists off to the new timeline, they...

    Year in review: Insect, bird evolution revisited

    14

    Biologists in 2014 saw what an astronomical amount of data could do for evolutionary questions — and what it couldn’t.

    Bernhard Misof of the Zoological Research Museum Alexander Koenig in Bonn...

    Mega volcanism indicted in dinosaur demise

    New dating of a colossal series of volcanic outpourings bolsters the idea that the Chicxulub asteroid impact had help in wiping out the dinosaurs 66 million years ago.

    Using crystals embedded in lava layers, geologists have deduced the most precise timing yet for the massive Deccan eruptions that poured out hundreds of thousands of cubic kilometers of molten rock in West India. The most...

    Epic worldwide effort explores all of insect history

    View the timeline

    By analyzing a locust swarm of data —1,478 genes from each of 144 kinds of insects and their relatives —a worldwide research team has reconstructed the tale of how insects arose and took over the Earth.

    The first insects may have appeared as early as 479 million years ago, 101 members of the 1KITE (1,000 Insect Transcriptome Evolution)...

    Early animals couldn’t catch a breath

    The diversification of early animals may have been suffocated by a lack of oxygen. A new analysis of ancient rocks offers a glimpse of conditions in the millions of years leading up to the proliferation of animals. The data suggest that oxygen levels were less than 1 percent of today’s levels, low enough that they may have stalled the emergence of animal life.

    Scientists have been...

    A timeline of a baby’s first hour

    Back when I worked in a lab, I spent countless hours diligently watching fruit flies mate. It was a strange job — both extremely scandalous and extremely boring. But lots of scientists are also voyeurs, I swear. And those tedious observations were a good way to learn about instinctual behaviors.

    So I was a little nostalgic when I came across a paper from scientists in Sweden. The...
