Proof that the people of Madagascar are of Indonesian origin. Genetics have provided evidence of the Polynesian DNA (mitochondrial) in Madagascar from remote Oceania and Y chromosome 'haplogroups' from south-east Asia and Oceania.

Sexual selection by Chemoattractants

Sexual selection by Chemoattractants

Posted Tue, 20 Mar 2012 23:01:00 GMT by Paul Robinson

In the history of science, sperm chemoattraction has long been recorded in a large variety of species, including plants. When a sperm can find an unfertilised egg more easily, sexual selection and a host of other efficient systems improve.

3D orientation does it for us and chicks

3D orientation does it for us and chicks

Posted Fri, 16 Mar 2012 13:00:27 GMT by Dave Armstrong

In extreme conditions or even in normal situations, an animal has to get itself back into the groove quickly after any disorientation. Survival normally depends on it. Your sense of place is dependent on either panorama-matching processes or by matching the actual 3D geometry of a place.

Life not so sweet for meat-eating mammals

Life not so sweet for meat-eating mammals

Some carnivores often lose their taste for sweet foods and mammals that swallow their food whole have little ability to taste, scientists have found.

With the genome of the western gorilla, a new paper has contrived successfully to contrast ourselves and other ape genomes as they have changed in evolution.

When we wrote on Oetzi the archer who became 'The Iceman,' we must have missed the point. Now geneticists have jumped into the glacier with him and extracted his DNA for a whole-genome sequence.

Could it be that elephants are our superiors in matrilocal (mother-based), hierarchical and complex social structures? Research into fossil elephant trackways investigates their behavior.

When we help each other, it's often voluntary and we can offer varying forms of understanding. Whether our closest relative can concur with his fellow chimpanzee (Pan troglodytes) when aiming for a goal could be a crucial question.

The north of China has some perfectly preserved forewings of Jurassic insects. What research has made possible is, by comparison with living Prophalangopsids (sort-of-crickets) and electron microscopy of the stridulation apparatus, a complete and convincing 'reconstruction' of the pure tone at 6.4kHz.

Mammal Evolution: Mouse to elephant-size in 24 million generations

It takes 24 million generations for a mammal the size of a mouse to become as large as an elephant, but just 100,000 generations to reverse the process and reach extreme dwarfism, say scientists studying mammal evolution.

Four massive tropical volcano eruptions started the Little Ice Age as early as 1275AD and caused cooling that lasted 500 years, say scientists.
