Zoology (UK: / z u ˈ ɒ l ə dʒ i / zoo-OL-ə-jee, US: / z oʊ ˈ ɒ l ə dʒ i / zoh-OL-ə-jee) [1] is the scientific study of animals.Its studies include the structure, embryology, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems.
Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million living animal species have been described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth.
As a result, each month now represents 1 of 12 billion years of the Earth's life. According to this calendar, the first life appears in January, and the first animals first appeared in May, with the present day taking place on May 18. Even though the Sun won't destroy Earth until December 31, all animals will die out by the end of May.
Many animals on this second table are at least somewhat altered from wild-type animals due to their extensive interactions with humans, albeit not to the point that they are regarded as distinct forms (therefore, no separate wild ancestors are noted) or would be unable to survive if reintroduced to the wild.
