How climate change could kill off reptiles

Global warming could threaten the survival of reptiles by reducing the number of bacteria living in their guts, researchers have found. According to Daily mail

They found that warming of 2-3°C (35-37°F) caused a 34 per cent loss of microorganism diversity in the guts of common lizards.

The researchers said that similar effect could be seen in other cold-blooded animals too, which depend on external sources of body heat.

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.
