In a recent study, researchers reveal that cougars may be making a comeback. The large felines originally suffered from habitat loss and hunting. Though, the animals may soon be able recolonize parts of the U.S. in as little as two decades.
Members of both animal and human social groups work together to hunt, forage and fight under the guidance of leader. A recent study took a closer look at the nature of leadership to better understand how human and non-human leaders promote cooperative actions.
Supercontinent Pangaea covered most of the Earth 278 million years ago and was home to animals unlike modern species. Researchers from The Field Museum describe several new amphibian species and a reptile that help paint a clearer picture of how diverse these ancient species really were.
To adapt to changing environments, fish have evolved with an enzyme researchers refer to as Cyp27c1, which is closely linked to vitamin A and known to promote good vision in low light.
Some butterflies have developed a toxic chemical that makes them poisonous to some birds. However, birds recognize which butterflies are lethal and avoid eating them. Since not all butterflies are equipped with such predatory defenses, they mimic their lethal counterparts and trick birds into thinking they are poisonous too.
A newly examined fossil sea urchin represents the oldest known specimen of its kind. This suggests that modern sea urchins diversified from their extinct ancestors ten million years earlier than researchers previously thought.
Rooftop bugs may provide valuable insight regarding climate change and how speceis adapt, relocate or die.
The discovery of a new speies of Malaysian snail has set the world record for tiniest land snail species. The previous record was set early this year by a species discovered in China.
Cowbirds lay their eggs in neighboring nests and abandon the to be raised by surrogate bird parents. Researchers recently spent some attempting to figure out whether the birds know they are different from their adopted families and how they handle it in terms of feeding, mating and flocking.
Iberian lynx fossils dating to 1.6 million years ago were recently recovered from a cave in Barcelona, Spain. It's the oldest lynx specimen ever found, suggesting the species arrived in the area 500,000 years earlier than originally estimated.
Aa currently evolve into two genetically distinct species as a result of apple trees changing their fruiting cycles, they're have a domino effect on predatory wasps, a process known as sequential speciation.
Researchers from the University of Alberta recently discovered fossilized tail feathers and soft tissues of an Ornithomimus dinosaur that shed light on the evolution of modern-day birds such as ostriches and emus.
Captured damselfish release a chemical distress call that confuses their attackers by calling other predators to the area. The ensuing competition buys them enough time to flee.
A study on a breed of farmbirds known as Plymouth Rock chickens suggests evolutionary differences can be observed on a much shorter time scale than previously thought.
