The Iberian ibex (Capra pyrenaica), also known as the Spanish ibex, Spanish wild goat and Iberian wild goat, is a species of ibex endemic to the Iberian Peninsula. [3] Four subspecies have been described; two are now extinct. The Portuguese ibex became extinct in 1892, and the Pyrenean ibex became extinct in 2000.
Capra pyrenaica pyrenaica taxidermy specimen – MHNT. The Pyrenean ibex (Capra pyrenaica pyrenaica), Aragonese and Spanish common name bucardo, Basque common name bukardo, Catalan common name herc and French common name bouquetin, was one of the four subspecies of the Iberian ibex or Iberian wild goat, a species endemic to the Pyrenees.
Three closely related varieties of goats found in the wild are not usually called ibex: the markhor, western tur, and eastern tur. A male ibex is referred to as a buck, a female is a doe, and young juveniles are called kids. [1] An ibex buck is commonly larger and heavier than a doe.
The Portuguese ibex (Capra pyrenaica lusitanica) is an extinct subspecies of Iberian ibex that inhabited the north mountainous zones of Portugal, Galicia, Asturias and western Cantabria. In size and colouration it was much like the Spanish animals, though inclining towards brown rather than black markings.
De-extinction (also known as resurrection biology, or species revivalism) is the process of generating an organism that either resembles or is an extinct species. [1] There are several ways to carry out the process of de-extinction. Cloning is the most widely proposed method, although genome editing and selective breeding have also been considered.
The horns grow throughout life. Young are born without horns, which become visible as tiny tips at one month and reach 20–25 mm (0.8–1.0 in) in the second month. [ 2 ] In males, the horns grow at about 8 cm (3.1 in) per year for the first five-and-a-half years, slowing to half that rate once the animal reaches 10 years of age. [ 5 ]
The first known mass extinction was the Great Oxidation Event 2.4 billion years ago, which killed most of the planet's obligate anaerobes. Researchers have identified five other major extinction events in Earth's history, with estimated losses below: [11] End Ordovician: 440 million years ago, 86% of all species lost, including graptolites
The worst Phanerozoic event, the Permian–Triassic extinction, devastated life on Earth, killing over 90% of species. Life seemed to recover quickly after the P-T extinction, but this was mostly in the form of disaster taxa, such as the hardy Lystrosaurus. The most recent research indicates that the specialized animals that formed complex ...
