History of Animals (Ancient Greek: Τῶν περὶ τὰ ζῷα ἱστοριῶν, Ton peri ta zoia historion, "Inquiries on Animals"; Latin: Historia Animalium, "History of Animals") is one of the major texts on biology by the ancient Greek philosopher Aristotle. It was written in sometime between the mid-fourth century BC and Aristotle's ...
Quadrupedalism is a form of locomotion where animals have four legs that are used to bear weight and move around. An animal or machine that usually maintains a four-legged posture and moves using all four legs is said to be a quadruped (from Latin quattuor for "four", and pes , pedis for "foot").
[2] [3] Estimates on the number of Earth's current species range from 10 million to 14 million, [4] with about 1.2 million or 14% documented, the rest not yet described. [5] However, a 2016 report estimates an additional 1 trillion microbial species, with only 0.001% described. [6]

Quadrupedal species normally synchronize the locomotor and respiratory cycles at a constant ratio of 1:1 (strides per breath) in both the trot and gallop. Human runners differ from quadrupeds in that while running they employ several phase-locked patterns (4:1, 3:1, 2:1, 1:1, 5:2, and 3:2), although a 2:1 coupling ratio appears to be favored.
The formal introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work Species Plantarum in 1753. [4] But as early as 1622, Gaspard Bauhin introduced in his book Pinax theatri botanici (English, Illustrated exposition of plants) containing many names of genera that were later adopted by ...
However, before this, the terms were familiar to the people of France as a slang word used by gamblers. The term is a derivative of the word 'masco' meaning sorceress or witch. Before the 19th century, the word 'mascot' was associated with inanimate objects that would be commonly seen such as a lock of hair or a figurehead on a sailing ship.
Although the first civilian GPS receivers were developed by Magellan in 1989, they were very large and therefore impractical for animal applications. By the mid-1990s, the larger GPS manufacturing companies created GPS receivers that were smaller, more energy-efficient, and therefore more usable for animal-tracking applications.
