As an interesting example of how 11,000 years of cohabitation can trump millions of years of common history, a group of scientists has recently found that chimpanzees are not as good at understanding us, or what we want, as dogs are.
The animals were put to an extremely simple test – a human pointed at an obj... |

Though not all dinosaurs were behemoths, some grew to be more than 100 feet (30 meters) tall. Experts have always wondered what made the creatures grow so tall, and now they are starting to form a picture of the factors that interacted to make this a reality.
Some of the contributing factors may sound weird at firs... |

A new investigation has revealed an interesting interaction between two evolutionary processes – natural selection and the founder effect. This has never been studied before in nature, but the phenomenon was discovered in a population of lizards living in a tiny island in the Bahamas.

Lifeforms need about 24 million generations to develop into something entirely different from what they once were; case in point: the rabbit-to-elephant transition. A new study found that this is the length of time needed to affect such impressive changes in a creature. The same study found that it takes about 100,... |

Even if gossip is generally frowned upon in society (by the same people who also practice it), it does have a number of benefits. Scientists demonstrate that it plays in important role in maintaining social order, as well as in policing negative behaviors that may otherwise spread.

A collaboration of experts from the University of Minnesota (UMN) says that it was recently able to shed more light on one of the most mysterious and important processes that allowed single-cells organisms to develop into multicellular clusters.

An analysis conducted on the fossilized remains of crickets and katydid that lived 50 million years ago revealed that these creatures evolved ears at a time when there were no predators to use them against.
Understandably, ears evolved as a defense mechanism in most species, allowing them to detect a predator while... |

Three newly- proposed bills seek to make the teaching of evolution obsolete in public classrooms. The documents call, in various forms, for the well-established theory to be thought as philosophy, rather than science, or for it to be interpreted as just another theory or idea.

Researchers were recently able to confirm one of the most important presuppositions about why certain species of deep-sea microorganisms glow in the dark. Apparently, the bacteria do so because they can then get a free ride to other parts of the ocean, inside the bellies of fish and other marine creatures.
The pro... |

Studies on the origins of Homo sapiens have revealed that our species most likely appeared in tree-dotted savannas, somewhere in central-eastern Africa. But a new proposal says that our ancestors may have evolved on the banks of major rivers as well.

Investigators have determined in a new study that certain types of frogs are able to encode information about how large their burrows are into the calls they send out to prospective mates. Their real estate thus becomes an extra reason for females to select them over their rivals.

Researchers established that animal and plant populations in areas of the world most likely to be affected by climate change in the very near future will have to adapt to their new environment at the same speed. If this is not an option, then they will have to abandon their territories just as fast.

The international scientific community knows a group of plants known as cycads for having lived at the same time the dinosaurs did, more than 65 million years ago.

Learning more about how each species or group of species evolved over time is a daunting task, especially considering that the fossil record is incomplete.
