Mbuzi wa ajabu mwenye jicho moja amezaliwa huko india, kijiji cha Assam, tarehe 10/5.
A strange goat with one large eye in the middle of its forehead was born in a village in Assam, India, on May 10.
The goat’s condition, called cyclopia, is characterized by the developing brain’s failure to separate into two hemispheres. As a result, the skull only forms a single eye socket.
Other defects usually accompany cyclopia. The young goat has only one complete ear, lacks a true nose, eyelids and eyelashes, and has jaws that are unusually small and missing teeth, causing the tongue which is a normal size to stick out on one side.
The term "Cyclops" originated with the Greek "KuklĹŤps," which means "round-eyed," and referred to a mythological race of one-eyed giants sired by the Greek ocean god Poseidon. Fossil discoveries of dwarf elephant skulls may have fueled myths of the monstrous Cyclops — the large nasal opening in the center of the pachyderm's skull could have been interpreted as the cavity for one enormous eye, the American Museum of Natural History explained on its website for the exhibit "Mythic Creatures."
Another goat with cyclopia ― that lived only 10 hours after birth ― was analyzed by scientists in a study published in 2014, in the Alexandria Journal of Veterinary Sciences. Researchers scanned the goat's head with computer X-ray tomography (CT) and conducted a necroscopy (animal autopsy). Like the goat born a few days ago, it had reduced and malformed jaws, and no nose, eyelids, eyelashes or upper teeth. The orbital opening, which held a single eyeball, measured about 1.2 inches (3 centimeters) in diameter.
It is unclear what causes cyclopia, though scientists have suggested it may be linked to toxins produced naturally by pregnant mothers, according to a study published in 1998 in the journal Science. Excessive leves of the toxins inhibit cholesterol's movement within a developing embryo, disrupting a signal that shapes a number of body parts in a growing fetus, including its face and brain, the study authors wrote.
Though rare, cyclopia has been reported in a variety of embryonic and newborn animals, including buffalo, cows, goats, sheep, deer and even humans, according to a study published in 2015 in the journal Clinical Medical Insights: Pediatrics.
In humans, cyclopia affects an average of one in every 100,000 births, the study authors reported. In all species, those born with these severe defects typically don't survive for long. The researchers of the 2015 study described the condition as "incompatible with life."
