When it comes to the animal kingdom, we often find ourselves marveling at the diversity of species that inhabit our planet. Regardless of our differences, the more we delve into the intricacies of genetics and biology, the more we realize just how interconnected all life on Earth truly is. One remarkable example of this interconnectedness is the relationship between humans, bonobos, and chimpanzees. Despite the differences in their "personality" traits, our DNA tells a compelling story of our shared ancestry with these incredible primates.

Bonobos and chimpanzees, our closest living relatives in the animal kingdom, are often viewed as two sides of the same evolutionary coin. While they share approximately 98 percent of their DNA with each ot ...

We often hear people say that modern birds evolved from some dinosaurs. Apart from both being reptiles, what evidence have paleontologist discovered that validates this claim?

A small bird-like dinosaur, called the archaeopteryx (left), lived in what is now southern Germany about 150 million years ago. About the size of a crow, it had a shortened tail, long hands, a perching toe slightly turned backward, and wing feathers that were adapted for flight. This creature has long been considered the most ancient bird known. However, despite its birdlike characteristics, its body more closely resembled those of small meat-eating dinosaurs than those of more birdlike dinosaurs. Many paleontologists identify the archaeopteryx as the so-called missing ...

To produce cellular energy, nearly all multicellular organisms use a series of highly specialized proteins embedded in the inner member of the mitochondria to transport and pump electrons, collectively known as the electron transport chain. A new study has revealed that this is not the case in European mistletoes, the traditional Christmas ornament hung to give someone a kiss underneath it.

After sequencing the organism's genome, researchers couldn't find any mitochondrial genes for coding the protein subunits that make up the electron transport chain’s first station, called complex I. To find out which parts of the assembly line machinery had disappeared, researchers extracted proteins from mitochondria in the mistletoe's leaves and compar ...

Rattlesnakes are a group of venomous snakes native to the Americas known for their loud rattling tail. The tip of their tail, known as the rattle (middle), vibrates to deter predators or serves as a warning to passers-by.

The rattle is composed of a series of hollow, interlocked segments made of keratin, which are created by modifying the scales that cover the tip of the tail. The contraction of special "shaker" muscles in the tail causes these segments to vibrate against one another, making the rattling noise (which is amplified because the segments are hollow) in a behavior known as tail vibration. The muscles that cause the rattle to shake are some of the fastest known, firing 50 times per second on average, sustained for up to three hour ...

Here's an explanation as to why humans have big bums (if you've ever thought about it )

This week in Science, researchers led by genome sequencing pioneer Craig Venter report engineering a bacterium to have the smallest genome - and the fewest genes - of any freely living organism. Known as Syn 3.0, the new organism has a genome whittled down to the bare essentials needed to survive and reproduce, just 473 genes. However, the function of 149 of Syn 3.0's 473 genes remain unknown.

As Syn 3.0's name suggests, it’s not the first synthetic life made by Venter. In 2010, Venter's team reported that they had synthesized the sole chromosome of Mycoplasma mycoides - a bacterium with a relatively small genome - and transplanted it into a separate mycoplasma called M. capricolum, from which they had previously extracted the DNA. After s ...

What sets Homo sapiens apart from other animals? Among other things, our chins do. That piece of bone sticking out from your jaw is somewhat of a mystery - one that's inspired a diversity of wild theories to explain its purpose, according to a paper published this month in Evolutionary Anthropology.

The author of the paper dismisses a number of these explanations, such as the possibility that the chin serves as a sexual signal (such traits usually only appear in one sex - like the mane of a male lion). Another proposal is that the chin acts to protect your throat - an idea the paper's author also shoots down, because for this to be a substantial advantage, humans would have to be constantly punching each other in the face.

So the mystery rem ...

Some of us may be guilty of procrastination, but we all are pre-crastinators at some level.

Procrastination is a serious problem to many of us that like to put off work and cram the night before. Not only is procrastination a behavioral problem, but also one with a psychological implication. Procrastination is the "thief of time". On the other hand, precrastination, discovered to be the complete opposite, is the tendency to do things ahead of time - and really ahead of time- just for the sake of completion.



Precrastination was found to be exhibited in pigeons as well. And the fact that we and pigeons have separated in phylogeny 300 million years ago suggests that precrastination is a behavior also found earlier in phylogeny. How has this be ...

Barry from Bee Movie has taught us that without bees, we won't survive. These pollinators may terrify us when they are swarming around out at the park, but they are more terrifying if they were not around.

What is happening to our bees with domestication? What have we lost? What are we trying to restore?

The answers to these questions are in this video. Check it out

A new study finds that Mudskipper fish carry water in their mouths in order to eat prey outside of water. As seen in the video below, the hidden water is expelled at the moment of eating and it serves as a suction to move the water and their meal back toward the esophagus. The water suction, or “hydrostatic” tongue, may serve as the evolutionary bridge that allowed our aquatic ancestors to begin feeding on land.

Here's how 9,000 years of selective breeding has changed corn from a wild grass - that required a hammer to peel - to the juicy yellow ears of deliciousness we know today.

Some species of lutung monkeys from Southeast Asia are born with bright orange coats. Called natal coats, they're thought to have evolved to stop adult males killing young males. In a rare subspecies, the golden coat is sometimes retained into adulthood.

The two marmosets - small, New World monkeys - had been a closely bonded couple for more than three years. Then, one fateful day, the female had a terrible accident. Her partner left two of their infants alone in the tree and jumped down to apparently comfort and mourn her. Humans mourn their dead, of course, and some recent studies have strongly suggested that chimpanzees do as well. This new observation suggests that mourning is more widespread among primates than previously thought.

The Buff-tip moth (Phalera bucephala) is a remarkable species that has developed a unique strategy to evade predators. When at rest, this moth cleverly disguises itself as a broken stick, blending seamlessly with its surroundings. The moth's wings are intricately patterned and colored to mimic the texture and appearance of a twig, complete with jagged edges and bark-like markings.

This exceptional camouflage allows the Buff-tip moth to remain virtually invisible to predators such as birds and small mammals that may otherwise consider it a potential meal. By adopting this disguise, the moth gains a significant advantage in survival, as it can confidently rely on its remarkable mimicry to go undetected in its natural habitat. This fascinating ...

Apes manage their emotions much in the same way as humans do. Socially and emotionally competent young bonobos recover quickly from upsetting experiences and are more likely to comfort other young apes, a new study has shown.

This is Migaloo, the albino white humpback whale. His name is derived from an Aboriginal word that means “white fella.” Migaloo is a favorite for whale watching enthusiasts. He is believed to be the only documented white humpback whale in the world.

He was discovered in 1991 and quickly became popular with tourists and locals alike. Since then, sightings have been rare. He migrates from Antarctica to Australia on a yearly basis, and some years he slips by undetected. Most of these photos were taken in 2012 on Migaloo’s return to Antarctica. ...

Four species of legless lizard have been identified in the sand dunes of Antioch, California. This picture introduces Anniella grinnelli, one of the recently found species. It has a bright yellow belly and a lilac back with deep purple lines, and was named after Joseph Grinnell, the first director of the Berkeley Zoology Museum.

This is Washoe, the first non-human to use sign language. When her caretaker Kat suffered a miscarriage, and Washoe was told that her baby had died, she signed "CRY", drawing a path down her cheek with her finger to mimic a tear. Chimpanzees don't shed tears, and Kat said this one sign told her more about Washoe's mental capabilities than all of her longer, grammatically perfect sentences.

Scientists have identified the genetic mutation responsible for the first blue chicken eggs in South American Mapuche fowl and their European descendants, Araucana, 200 to 500 years ago.

They used the unique genetic resources conserved by heritage or “fancy” poultry breeders to identify the exact location of the mutation in the genome in blue egg laying chickens and an additional genomic study to reveal the genetic cause of the blue colored eggshell is a harmless ancient retrovirus in the domestic chicken.

A bonsai tree is “trained” to grow as a dwarf by pruning and shaping the branches. But seeds from the tree would produce trees that grow to normal size. This shows the there is no inheritance of the characteristics acquired by pruning.

The tail was discovered in northern Mexico and most likely belonged to a hadrosaur, a duck-billed dinosaur. The tail is 4.9 meters (16 feet) long and is made up of 50 vertebrae. Tails are rare finds, and this is the first discovered in such good condition.

The arctic fox population on Mednyi Island in the Bering Sea has declined to just 100 individuals over the past 40 years, and a new study has found out why. It's likely due to mercury pollution in seabirds and fish, not infectious disease, as previously thought. This is important, say the researchers, because we eat marine food too, so we should stop and think about how much pollution is going into our Arctic waters.

At first, it just looks like a worm. But when you peek closer, it slithers like a snake. It sticks its tongue out like a snake. It creeps you out like a snake.

Discovered under a rock in 2006 in Barbados, this thread snake is as thin as spaghetti and smaller than any of the 3,100 other known snake species. Researchers believe it is the smallest a snake can evolve to be.
