Baby humpback whales 'whisper' to mums to avoid predators

The humpback whale is known for its loud haunting songs, which can be heard 20 miles away. According to BBC

However, new recordings show mothers and calves "whisper" to each other, seemingly to avoid attracting predators.

The quiet grunts and squeaks can be heard only at close range.

By calling softly to its mother, the calf is less likely be overheard and preyed on by killer whales, scientists believe.

Dr Simone Videsen is part of a team of scientists who tracked eight baby whales and two mothers to learn more about the first months of a humpback whales life.

'World's oldest fungus' raises evolution questions

Fungus-like life forms have been found in rocks dating back 2.4 billion years. According to BBC

The fossils, drilled from rocks that were once beneath the seafloor, resemble living fungi.

Scientists say the discovery could push back the date for the oldest fungi by one to two billion years.

Unknown ancient reptile roamed the mountains

The footprints of a mysterious reptile that lived about 250 million years ago have been identified in fossils from the Pyrenees mountains.

Scientists say the new species is a member of the group that gave rise to crocodiles and dinosaurs. According to BBC

The reptile lived at a time when the Earth was recovering from a mass extinction that wiped out most animals.

The discovery may shed light on how the group of animals evolved and spread.

Sea scorpions: The original sea monster

Four hundred and thirty million years ago, long before the evolution of barracudas or sharks, a different kind of predator stalked the primordial seas. The original sea monsters were eurypterids -- better known as sea scorpions. According to Science daily

Related to both modern scorpions and horseshow crabs, sea scorpions had thin, flexible bodies. Some species also had pinching claws and could grow up to three metres in length. New research by scientists Scott Persons and John Acorn hypothesise that the sea scorpions had another weapon at their disposal: a serrated, slashing tail spin.

How domestication can change animals' facial features

Domesticated animals, compared to their wild counterparts, have undergone numerous changes in physiology, behavior and morphology. These changes are commonly referred to as the domestication syndrome and include behavioral changes, such as increased docility as well as genetic alterations in size, color and facial characteristics. In attempting to find whether these changes have a single cause, zoologist Dmitry Belyaev conducted a series of selection experiments with silver foxes, hypothesizing that behavior, specifically tameness, was the key driving factor behind the changes brought about by domestication. After generations of selecting foxes for tameness, they were found to display phenotypes similar to those observed in domesticated species. Since then, it has been further hypothesized that selection for social tolerance and reduced aggression may also have played an important role in shaping the modern human anatomy, which is remarkable for the reduced face and gracile overall features.
