The idea that a chimpanzee and human can interbreed, forming a hypothetical hybrid species known as a humanzee, is not uncommon. Since chimpanzees and humans are closely related species (sharing 95% of their DNA sequence, and 98% of coding DNA sequences), it has lead to contested speculation that a hybrid is possible, though no specimen has ever been confirmed.
While there is a commonality in gene sequence between us and chimpanzees, humans still have one fewer pair of chromosomes (46 chromosomes) than other apes (48 chromosomes). This makes conception between the two species naturally impossible. However, a different numbers of chromosomes is not an absolute barrier to hybridization. Similar mismatches are relatively common in existing spec ...
Sky gazers will be treated to a rare convergence of celestial events on 31 January — a blue moon, a supermoon, and a total lunar eclipse, all in one. The phenomenon, which hasn’t happened since 1866, graces the sky when the second full moon of the month (known as a blue moon) is in its closest position to Earth, making it appear even larger than usual — a supermoon.
The seldom-seen event will be visible in western North America, Asia, Australia, and elsewhere across the Eastern Hemisphere. So, if you’re in one of those lucky locations and want to see an event that’s literally once in a blue moon, here’s your chance.
Researchers have found that roosters produces 1 to 2 second crows that can get as loud as 143 decibels. This is equivalent to standing 15 meters away from a jet taking off.
But if that's the case, how do roosters and surrounding chickens tolerate this noise?
Researchers have found that when a rooster’s beak is fully open, as it is when crowing, a quarter of the ear canal completely closes and soft tissue covers 50% of the eardrum. This means roosters aren’t capable of hearing their own crows at full strength. The intensity of a rooster’s crow diminishes greatly with distance, so it probably doesn’t cause significant hearing loss in nearby hens. Interestingly, unlike mammals, birds ca ...
Well, obviously it's white, but take a look at its bill!
The attractive 7.5-inch-long bill is possessed by both male and female toucans. Interestingly, they use them during a mating ritual, pitching fruit to one another, but has very limited use as an excavation tool. Toucans make their nests in tree hollows found in rain forest regions of Southern Mexico, Central and South America, and the Caribbean region to which they are native.
