'Telepathic' genes recognize similarities in each other
Genes have the ability to recognise similarities in each other from a distance, without any proteins or other biological molecules aiding the process, according to new research published this week in the Journal of Physical Chemistry B. This discovery could explain how similar genes find each other and group together in order to perform key processes involved in the evolution of species.

Mothers Trade Child Quantity For Quality
Researchers at the University of Sheffield have shown that mothers are choosing to have fewer children in order to give their children the best start in life, but by doing so are going against millenia of human evolution. The research sheds new light on the decline of modern day fertility.

96-million-year-old Fossil Pollen Sheds Light On Early Pollinators
The collapse of honeybee colonies across North America is focusing attention on the honeybees’ vital role in the survival of agricultural crops, and a new study by University of Florida and Indiana University Southeast researchers shows insect pollinators have likely played a key role in the evolution and success of flowering plants for nearly 100 million years.

Platypus fossil suggests slow evolution
New evidence from 100-million-year-old jawbones found in Australia suggests that egg-laying mammals such as the platypus may have evolved more slowly than other mammals

Evolution of the sexes: What a fungus can tell us
Fungi don't exactly come in boy and girl varieties, but they do have sex differences. In fact, a new finding from Duke University Medical Center shows that some of the earliest evolved forms of fungus contain clues to how the sexes evolved in higher animals, including that distant cousin of fungus, the human.

New Model Of Competitive Speciation Unifies Insights From Earlier Work
Under which circumstances is sympatric speciation possible? An answer to this long-standing question of evolutionary biology has turned out to be challenging. In particular, models for the evolution of assortative mating under frequency-dependent disruptive selection necessarily depend on a large number of ecological and genetic factors.

Is Homosexuality an Evolutionary Step Towards the Superorganism?
Only by conceiving of evolution as acting upon entire populations rather than individual organisms can we understand eusociality -- the mysterious, seemingly "altruistic" behaviors exhibited by insects who forego reproduction in order to care for a colony's young.

2 explosive evolutionary events shaped early history of multicellular life
Scientists have known for some time that most major groups of complex animals appeared in the fossils record during the Cambrian Explosion, a seemingly rapid evolutionary event that occurred 542 million years ago. Using rigorous analytical methods, have identified another explosive evolutionary event that occurred about 33 million years earlier.
