The World's Smallest Reindeer Are Fluffy Cutie Pies   IFL Science - December 24, 2024

Introducing the Svalbard Reindeer (Rangifer tarandus platyrhynchus), which are around 1.5-1.6 meters (4.9-5.2 feet) long. These cuties are wild, non-domesticated reindeer endemic to the Norwegian Svalbard archipelago in the Arctic Ocean. In winter, they look adorable with thick fluffy light grey or yellow-white fur. In the summer, they look darker, and their fur is less thick. These reindeer have short legs, and relatively small, rounded heads.

The Nile crocodile (Crocodylus niloticus) has lived at the Crocworld Conservation Centre in Scottburgh, South Africa since 1985. He was originally captured in the Okavango Delta in Botswana in 1903. Henry, now a vigorous senior resident at the Crocworld Conservation Center, is said to have fathered over 10,000 offspring with numerous partners since he arrived there almost 40 years ago.

Scientists Discover a Mysterious 'Sixth Sense' Hidden in Geckos   Science Alert - October 11, 2024

Animals have come up with a variety of extraordinary senses worthy of superheroes. Scientists have now discovered that geckos boast a hidden 'sixth sense' that lets them pick up deep, low vibrations. Like other lizards, tokay geckos (Gekko gecko) have hearing that's specialized towards higher frequency sounds - they're most sensitive between 1,600 and 2,000 Hertz, but can hear beyond 5,000 Hertz. That's just using their regular old ears, though. Two researchers have found that tokay geckos can also use a different structure, not normally associated with hearing, to sense much lower frequency vibrations, in the range of 50 to 200 Hertz.

Incredible Discovery Has Finally Revealed The First Animals to Grow a Skeleton   Science Alert - November 7, 2022

Before life on Earth exploded in diversity some 540 million years ago, the first primitive animal skeletons were already starting to form. Squishy-looking marine sponges from this time have been found in tubular thimble-like shapes, structured by hard, mineralized threads - specimens that are thought to be among the earliest assemblages of skeletal fossils.

1st bioengineered hybrid animals discovered - in ancient Mesopotamia   Live Science - January 14, 2022
Mesopotamians were using hybrids of domesticated donkeys and wild asses to pull their war wagons 4,500 years ago at least 500 years before horses were bred for the purpose, a new study reveals. The analysis of ancient DNA from animal bones unearthed in northern Syria resolves a long-standing question of just what type of animals were the "kungas" described in ancient sources as pulling war wagons.

Genetic Tracing Reveals Where The Powerful Ancestor of Modern Horses Came From   Science Alert - October 21, 2021
The ancestral homeland of all modern domestic horses was likely located along the steppes of Western Eurasia around 4,200 years ago, according to new genetic research. 'Within just 1,000 years, the powerful and docile horses raised here, in what is now modern Russia, seem to have replaced all the other breeds in Europe and Asia.

Killing of White Spirit Moose Brings Warnings of Bad Luck   Mysterious Universe - November 18, 2020
Being an albino in this world is a tough life - and that's not just for humans. Animals with albinism or other forms of pigment problems are generally weaker and more prone to being preyed upon because they have a much harder time hiding. Being white has also made them mystical to many cultures, which should help to protect them but often does not. That's the sad story from Timmins, in northern Ontario, where residents found a rare white 'spirit' moose slaughtered and dumped on a deserted road. Animal rights people are outraged, authorities are hunting for the poachers and local indigenous people are warning that the killers are facing a rash of bad luck or worse.

World's only known white giraffe fitted with tracker to deter poachers   BBC - November 18, 2020
The world's only known white giraffe has been fitted with a GPS tracking device to keep poachers at bay in north-east Kenya, conservationists say. A conservation group said rangers could monitor the lone male giraffe's movements in real time. The giraffe has a rare genetic condition called leucism, which causes the loss of skin pigmentation. He is thought to be the last of his kind, after poachers killed two of his family members in March.

Was Same-Sex Behavior Hardwired in Animals from the Beginning?   Live Science - November 21, 2019
Evolutionary scientists have been thinking about same-sex sexual behavior all wrong. That's the implication of a new study on same-sex behavior in animals. Instead of asking why animals engage in same-sex behavior (SSB), researchers should be asking, "Why not?" the authors said. If they're right, same-sex sex may not have evolved independently in different animals for adpative reasons. Instead, same-sex sex may have emerged very early in time and could persist simply because engaging in it doesn't cost animals much, evolutionarily speaking.

How animals stand together in times of trouble Ð just like humans: Threat of 'war' from rival packs unites dwarf moongooses   Daily Mail - June 20, 2019

How the horse became the only living animal with a single toe   The Guardian - August 23, 2017
They can reach speeds of more than 40km an hour, clear hurdles more than eight feet high and even pirouette Ð and they manage it all with just one toe on each foot. Now researchers say they have unpicked how and why horses ended up with their unusual extremities. The only living animals with a single toe, equines (such as horses and zebras) had ancestors with multiple digits on their feet, with early relatives having four on their front feet and three on their back. While it has long been thought that the shift was linked to horses moving from forest to grassland environments, it was unclear how this anatomical change happened. Now researchers say they have cracked the conundrum.

Meet Granddad: Weird, Ancient Reptile Gave Rise to Mammals   Live Science - October 5, 2016
Two weird, mammal-like reptiles that sort of looked like scaly rats, each smaller than a loaf of bread, roamed ancient Brazil about 235 million years ago, likely dining on insects the predators snagged with their pointy teeth, a new study finds. The analysis of two newfound species of cynodont, a group that gave rise to all living mammals, sheds light on how mammals developed from these late Triassic creatures, the researchers said.

Horses can communicate with us - scientists   BBC - September 24, 2016
Horses have joined a select group of animals that can communicate by pointing at symbols. Scientists trained horses, by offering slices of carrot as an incentive, to touch a board with their muzzle to indicate if they wanted to wear a rug. The horses' requests matched the weather, suggesting it wasn't a random choice. A few other animals, including apes and dolphins, appear, like us, to express preferences by pointing at things.

Lizards share sleep patterns with humans   BBC - April 29, 2016
Until now, it was thought features of human sleep such as rapid eye movements were seen only in mammals and birds. Now, a study of the bearded dragon - a popular pet - suggests these distinctive sleep rhythms emerged hundreds of million of years ago in a distant ancestor.

Horses can read human emotions, study shows   PhysOrg - February 10, 2016
For the first time horses have been shown to be able to distinguish between angry and happy human facial expressions. Psychologists studied how 28 horses reacted to seeing photographs of positive versus negative human facial expressions. When viewing angry faces, horses looked more with their left eye, a behavior associated with perceiving negative stimuli. Their heart rate also increased more quickly and they showed more stress-related behaviors.

Zebra cousin went extinct 100 years ago. Now, it's back   CNN - January 27, 2016
Never heard of the quagga? You're not alone. The animal, a relative of the zebra, went extinct over 100 years ago. Now, a group of scientists outside of Cape Town are bringing it back. Like zebras, the quagga has stripes, though these only appear on the front half of their bodies. Unlike the zebra, they are brown along the rear half of their body. These animals used to roam South Africa in vast herds, but European settlers fixed the beasts in their sights, killing them at an alarming rate. By the 1880s, the last known example had died. Now, however, scientists have bred an animal that looks strikingly similar with the help of DNA and selective breeding.

Researchers discover first sensor of Earth's magnetic field in an animal   PhysOrg - June 17, 2015
A team of scientists and engineers at The University of Texas at Austin has identified the first sensor of the Earth's magnetic field in an animal, finding in the brain of a tiny worm a big clue to a long-held mystery about how animals' internal compasses work. Animals as diverse as migrating geese, sea turtles and wolves are known to navigate using the Earth's magnetic field. But until now, no one has pinpointed quite how they do it. The sensor, found in worms called C. elegans, is a microscopic structure at the end of a neuron that other animals probably share, given similarities in brain structure across species. The sensor looks like a nano-scale TV antenna, and the worms use it to navigate underground.

Intact Ottoman 'war camel' found in Austrian cellar   CNN - April 1, 2015
A complete camel skeleton dug up from a 17th-century Austrian cellar shows tell-tale signs that it was a valuable riding animal in the Ottoman army. It was probably left behind or traded in the town of Tulln following the Ottoman siege of nearby Vienna in 1683. DNA analysis shows that the beast - the first intact camel skeleton found in central Europe - was a Bactrian-dromedary hybrid, popular in the army. It also has bone defects that suggest it wore a harness and was ridden.

The lion hugger   BBC - March 26, 2015
In 2012 Valentin Gruener rescued a young lion cub and raised it himself at a wildlife park in Botswana. It was the start of an extraordinary relationship. Now an astonishing scene is repeated each time they meet - the young lion leaps on Gruener and holds him in an affectionate embrace. "Since the lion arrived, which is three years now, I haven't really left the camp," says Gruener. "Sometimes for one night I go into the town here to organize something for the business, but other than that I've been here with the lion." The lion he has devoted himself to is Sirga - a female cub he rescued from a holding pen established by a farmer who was fed up with shooting animals that preyed on his cattle. "The lions had killed the other two or three cubs inside the cage, and the mother abandoned the remaining cub. She was very tiny, maybe 10 days old," Gruener says. "I don't believe we have to teach the lion to hunt. They have this instinct like a domestic cat or even a dog that will try to hunt. Any cat will catch a bird or a mouse. The lion will catch an antelope when it gets big enough," Gruener says.

Chameleon colors 'switched by crystals'   BBC - March 11, 2015
Swiss researchers have discovered how chameleons accomplish their vivid color changes: they rearrange the crystals inside specialized skin cells. It was previously suggested that the reptiles' famous ability came from gathering or dispersing colored pigments inside different cells. But the new results put it down to a "selective mirror" made of crystals. They also reveal a second layer of the cells that reflect near-infrared light and might help the animals keep cool.

Reshaping the horse through millennia: Sequencing reveals genes selected by humans in domestication   Science Daily - December 15, 2014
Whole genome sequencing of modern and ancient horses unveils the genes that have been selected by humans in the process of domestication through the last 5,500 years, but also reveals the cost of this domestication. An international research group reports that a significant part of the genetic variation in modern domesticated horses could be attributed to interbreeding with the descendants of a now extinct population of wild horses. This population was distinct from the only surviving wild horse population.

Biologists map crocodilian genomes   Science Daily - December 11, 2014

Horses' mobile ears are 'communication tool'   BBC - August 5, 2014
Very mobile ears help many animals direct their attention to the rustle of a possible predator. But a study in horses suggests they also pay close attention to the direction another's ears are pointing in order to work out what they are thinking. Researchers from the University of Sussex say these swiveling ears have become a useful communication tool.

Dog People vs. Cat People: Who's More Outgoing? More Intelligent?   Live Science - May 27, 2014
"Dog people" and "cat people" really do have different personalities, according to a new study. People who said they were dog lovers in the study tended to be more lively - meaning they were more energetic and outgoing - and also tended to follow rules closely. Cat lovers, on the other hand, were more introverted, more open-minded and more sensitive than dog lovers. Cat people also tended to be non-conformists, preferring to be expedient rather than follow the rules. And in a finding that's sure to spark rivalries among pet owners, cat lovers scored higher on intelligence than dog lovers.

Modern lions' origin revealed by genetic analysis   BBC - April 2, 2014
The origin and history of modern lions have been revealed by scientists. A genetic analysis of living lions and museum specimens confirms modern lions' most recent common ancestor lived around 124,000 years ago. Modern lions evolved into two groups; one lives in Eastern and Southern Africa, the other includes lions in Central and West Africa, and in India. This second group is now endangered, meaning half the genetic diversity of modern lions is at risk of extinction.

Scientists solve the riddle of zebras' stripes: Those pesky bugs   Science Daily - April 1, 2014
Why zebras have black and white stripes is a question that has intrigued scientists and spectators for centuries. The scientists found that biting flies, including horseflies and tsetse flies, are the evolutionary driver for zebra's stripes. Experimental work had previously shown that such flies tend to avoid black-and-white striped surfaces, but many other hypotheses for zebra stripes have been proposed since Alfred Russel Wallace and Charles Darwin debated the problem 120 years ago.
