A fascinating looking whale
|
view preview
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. ...

A parrot with a wicked hairstyle
|
view preview
This is a Palm Cockatoo, also know as the Goliath Cockatoo. Palms are distinguished by their size, huge beak (second only to the Hyacinth Macaw among psittacines and largest proportionate to size), solid black feather coloration, large open crest, bare red cheeks, and red and black tongue. You have to see their tongues to believe the coloration. It's amazing. Palm Cockatoos are severely threatened. They are CITES Appendix I birds and are protected in Australia. As a testament to their rarity, typical prices in the U.S. for Aterrimus Palms are around $8000 and Goliaths around $14,000. Perhaps contributing to their rarity is the fact that, according to both Low and Forshaw, they lay only one egg per clutch. ...

All corn today, as we know corn, is GMO corn

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.

An essential bone lost
|
view preview
Despite slang terms that imply otherwise, the human penis contains no bones. The same cannot be said for many of our closest evolutionary relatives: Chimpanzees and bonobos both have penis bones (a macaque one is pictured, left), also known as bacula. To find out why some primates have the feature whereas others don’t, researchers traced the bone’s evolutionary history through time. The baculum first evolved between 145 million and 95 million years ago, as reported in the Proceedings of the Royal Society B. That means it was present in the most recent common ancestor of all primates and carnivores. Why some descendants, like humans, lost their bacula appears to be due to differences in mating practices: In primates, the presence of a penis ...

Barbados thread snakes
|
view preview
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.

Bees up-close
|
view preview
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

Being afraid of the dark is totally normal
|
view preview
Even though being afraid of the dark sounds childish, our fear of the dark is an evolutionary trait that we picked up to survive real-life predators stalking the night. Researchers have hypothesised that this innate fear stems from a point of human history when we were nowhere near the top predators we are today. Humans only really became super predators with the advent of technology, which wasn’t that long ago. Before technology, our ancestors were constantly on the look-out for predators that wanted nothing more than to chow down on human sandwiches. To make that even scarier, most of these predators hunted at night - a time of day when we are especially vulnerable to attack because of our relatively poor eyesight. This means that it was ...

Blue eggs
|
view preview
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. ...

Bonobos, Chimpanzees, and the 98% DNA Link
|
view preview
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 ...

Breastfeeding guidelines for neanderthals
|
view preview
Ancient baby's teeth have revealed that Neanderthals followed today's breastfeeding guidelines. Scientists analyzed a fossilized baby tooth from a Neanderthal child, and found the infant was breastfed exclusively for the first seven months of life and given supplementary foods and mother's milk for another seven months before being weaned. This fascinating discovery sheds light on the remarkable similarities between Neanderthal parenting practices and contemporary breastfeeding guidelines. By examining the composition of the fossilized baby tooth, scientists have uncovered valuable insights into the dietary patterns of our ancient relatives. The Neanderthal infant's exclusive breastfeeding for the first seven months of life mirrors the advice ...

Can anyone whisper, evolution?
|
view preview
Zookeepers at Central Park Zoo in the US assumed their cotton-top tamarins were falling silent every time someone entered their enclosure, but spectrograms, which provide visual representations of sound, revealed what was really going on. These little monkeys were actually whispering their alarm calls instead of shouting them, which is the first evidence of whispering in a non-human primate species.
