It is interesting to contemplate an entangled bank, clothed with many plants of many kinds, with birds singing on the bushes, with various insects flitting about, and with worms crawling through the damp earth, and to reflect that these elaborately constructed forms, so different from each other, and dependent on each other in so complex a manner, have all been produced by laws acting around us. These laws, taken in the largest sense, being Growth with Reproduction; Inheritance which is almost implied by reproduction; Variability from the indirect and direct action of the external conditions of life, and from use and disuse; a Ratio of Increase so high as to lead to a Struggle for Life, and as a consequence to Natural Selection, entailing Divergence of Character and the Extinction of less-improved forms. Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows.
The Christopher Hitchens WebWhitePagesGoesGreen.org by YellowPagesGoesGreen.org (Yellow Pages Directory Inc.) is a leading online directory allowing users to search an online database and telephone directory for all telephone numbers in the USA. Using the above boxes, simply type in a name and location. Even if you don't have the complete information, the telephone number lookup database can help you find phone numbers.PharyngulaProbably not. But the New York Times reports: A review of studies has found that the health benefits of infant male circumcision vastly outweigh the risks involved in the procedure. Actually, it doesn’t. Not at all. The paper is all about the frequency of circumcision in the US; this is the only real data in the paper, and notice that a good chunk of it is speculation.
Lectures de pensée animaleIl y a une dizaine d'années encore, la littérature sur les animaux disponible en langue française se composait essentiellement de titres tels que Jeannot Lapin va à l'école ou Rosalie la tortue qui fait plouf. Les temps changent. De préoccupation puérile, la question animale est passée au rang de sujet de publications intellectuellement respectables. On évoquera ici quelques-uns des ouvrages qui en témoignent parmi ceux qui ont un lien direct avec le thème principal de ce numéro des Cahiers (la sensibilité, la conscience) : À quoi pensent les animaux ? de Marc Hauser ; Les origines animales de la culture de Dominique Lestel ; Comment l'esprit vient aux bêtes et Les animaux pensent-ils ?
Black TriangleBy Anthony - Last updated: Thursday, July 4, 2013 If anyone is reading this, I now blog at anthonycox.org Many thanks. Anthony By Anthony - Last updated: Monday, February 13, 2012Bad AstronomyWell now, this is an interesting discovery: astronomers have found what looks like a "super-Earth" – a planet more massive than Earth but still smaller than a gas giant – orbiting a nearby star at the right distance to have liquid water on it! Given that, it might – might – be Earthlike. This is pretty cool news. We’ve found planets like this before, but not very many!
What's wrong with Gillian McKeith by Ben GoldacreCall her the Awful Poo Lady, call her Dr Gillian McKeith PhD: she is an empire, a multi-millionaire, a phenomenon, a prime-time TV celebrity, a bestselling author. She has her own range of foods and mysterious powders, she has pills to give you an erection, and her face is in every health food store in the country. Scottish Conservative politicians want her to advise the government. The Soil Association gave her a prize for educating the public. And yet, to anyone who knows the slightest bit about science, this woman is a bad joke.
paleoanthropology, genetics and evolutionI have a review of Marlene Zuk's new book, Paleofantasy , in this week's Nature : "Evolutionary biology: Twisting the tale of human evolution"  . I can't replicate my review here, but for people who have access to Nature I thought I'd bring attention to it. And if you don't have access, I wanted to share a couple of my reactions. It was a fun book for me to read. Zuk brings a light-hearted skepticism to a broad array of topics in human evolution. She took as her focus a collection of "paleo-advice" ideas: barefoot running, paleo diet, back-to-nature parenting advice.
The LoomYour hands are, roughly speaking, 360 million years old. Before then, they were fins, which your fishy ancestors used to swim through oceans and rivers. Once those fins sprouted digits, they could propel your salamander-like ancestors across dry land. Fast forward 300 million years, and your hands had become fine-tuned for manipulations: your lemur-like ancestors used them to grab leaves and open up fruits. Within the past few million years, your hominin ancestors had fairly human hands, which they used to fashion tools for digging up tubers, butchering carcasses, and laying the groundwork for our global dominance today. We know a fair amount about the transition from fins to hands thanks to the moderately mad obsession of paleontologists, who venture to inhospitable places around the Arctic where the best fossils from that period of our evolution are buried.

Pinning down when specific events occurred is often tricky, though. For this, biologists depend mainly on dating the rocks in which fossils are found, and by looking at the "molecular clocks" in the DNA of living organisms.
