Hominins and their closest living relative, chimpanzees, diverged approximately 6.5 million years ago on the African continent. Fossil evidence suggests hominins have migrated away from Africa at least twice since then. Crania of the first wave of migrants, such as Neanderthals in Europe and Peking Man in East Asia, show distinct morphological features that are different from contemporary humans (also known as Homo sapiens sapiens).

Conservation physiology was first identified as an emerging discipline in a landmark paper by Wikelski and Cooke, published in Trends in Ecology and Evolution in 2006. They defined it as “the study of physiological responses of organisms to human alteration of the environment that might cause or contribute to population decline”.

Do conservation genetics and ancient Greek history ever cross paths? Recently, a genetic study of a remnant population of elephants in Eritrea has also addressed an ancient mystery surrounding a battle in the Hellenistic world.

It doesn’t matter whether or not you think it’s fair: if you’re an academic, your publishing record will have a crucial impact on your career. It can profoundly affect your prospects for employment, for winning research grants, for climbing the academic ladder, for having a teaching load that doesn’t absorb all your time, for winning academic prizes and fellowships, and for gaining the respect of your peers.

My first job after veterinary school in 1983 was for the International Whaling Commission examining the efficacy of explosive harpoons for killing fin whales on an Icelandic whaling vessel. Later, I encountered a very different way of killing whales.

The United Kingdom is experiencing a period of extreme rainfall and an onslaught of Atlantic storms. This has resulted in extensive and prolonged flooding of the Somerset Levels and a rise in the levels of the River Thames not seen for over 60 years, flooding many homes for the first time since these were built.

Getting ready for work the other morning, I was diverted from pouring my coffee by the television news. A comet was about to pass near the sun and might, if it survived, become visible on earth. The professor of astrophysics who had been brought on to explain the details was engaging, enthusiastic and clear. She was a woman. I wondered how many school girls had heard her and been inspired. Fifty years ago, the idea of a woman gaining recognition in such an arcane area of science would have been astounding.

Embryologists who study the beginning of life, and gerontologists who study its end, interact rather little. This is hardly surprising: the former work with growth, construction and preparation for the long life ahead, while the latter work with loss, decline, and the inevitable journey to oblivion.
February 12th has been coined Darwin Day because it marks the anniversary of the birthday of Charles Darwin. One could come up with several creative ways to celebrate the life of such an influential and revered scientist—baking a cake with 73 candles in honor of Darwin’s 73 years of life, or taking a walk through a local park or nature reserve in an attempt to make observations about wild animals, to name a few.

This past November, the International Union for the Conservation of Nature declared the western black rhinoceros of Africa, last seen in 2006, officially extinct. It also concluded that most other rhino species are in danger, even “teetering.” Yet at the same time, over the past year, some scientists and others have been declaring that the woolly rhino – last seen, oh, 10,000 years or so ago – could soon NOT be extinct.
Have you ever wondered how a snake slithers up a tree, captures prey far larger than the size of its jaw, or sheds all of its skin? Not many people give these reptiles a second thought.

Understanding the internal organs of extinct animals over 100 million years old used to belong in the realm of impossibility. However, during recent decades exceptional discoveries from all over the world have revealed elusive details such as fossilized feathers, skin, and muscle.

When scientists in Scotland announced the successful cloning of Dolly the Sheep in 1997, it triggered a frenzy of speculation in the global media about the possibility of human cloning, and elevated ethical questions to the fore of public discussions about biotechnology. This debate had far-reaching consequences, with citizens’ perceived moral objections to human cloning contributing to the imposition of restrictive policies on stem cell research that involves the cloning of embryos.

Fractal shapes, as visualizations of mathematical equations, are astounding to look at. But fractals look even more amazing in their natural element—and that happens to be in more places than you might think.

Despite their wide usage, global fisheries catch data compiled by the United Nations Food and Agriculture Organization (FAO) are questionable.

Science and religion don’t generally get along very well, from the Catholic Church’s denunciation of the heliocentric solar system to vigorous denials — mostly from fundamentalist Protestantism this time — of evolution by natural selection.
