Darwin's theory was rapidly accepted by the scientific community and soon became a central axiom of the rapidly developing science of biology. The basis for modern genetics began with the work of Gregor Mendel on peas in 1865, although the significance of his work was not realized at

2006-406: A new perspective on the fundamental basis of life. Having previously been the realm of gentlemen naturalists, over the 18th, 19th and 20th centuries, zoology became an increasingly professional scientific discipline .

2124-467: A practice imposed by the Canadian Radio-television and Telecommunications Commission in which a pay television provider supplants an American station's signal with a feed from a Canadian station/network airing a particular program in the same time slot to protect domestic advertising revenue. Some of these affiliates are also receivable over the air in southern areas of the country located near

2242-709: A process involving the union of a male and female haploid gamete , each gamete formed by meiosis . Ordinarily, gametes produced by separate individuals unite by a process of fertilization to form a diploid zygote that can then develop into a genetically unique individual progeny. However, some animals are also capable, as an alternative reproductive process, to reproduce parthenogenetically. Parthenogenesis has been described in snakes and lizards (see Misplaced Pages Parthenogenesis in squamates ), in amphibians (see Misplaced Pages Parthenogenesis in amphibians ) and in numerous other species (see Misplaced Pages Parthenogenesis ). Generally, meiosis in parthanogenetically reproducing animals occurs by

Molecular genetics , the study of gene structure and function, has been among the most prominent sub-fields of molecular biology since the early 2000s. Other branches of biology are informed by molecular biology, by either directly studying

4012-698: Is reflected in zoology by the presence of animals in Egyptian hieroglyphics. Although the concept of zoology as a single coherent field arose much later, the zoological sciences emerged from natural history reaching back to the biological works of Aristotle and Galen in the ancient Greco-Roman world . In the fourth century BC, Aristotle looked at animals as living organisms, studying their structure, development and vital phenomena. He divided them into two groups: animals with blood, equivalent to our concept of vertebrates , and animals without blood, invertebrates . He spent two years on Lesbos , observing and describing

4130-559: Is the genus, and sapiens the specific epithet, both of them combined make up the species name. When writing the scientific name of an organism, it is proper to capitalize the first letter in the genus and put all of the specific epithet in lowercase.

Its studies include the structure , embryology , classification , habits , and distribution of all animals, both living and extinct , and how they interact with their ecosystems . Zoology is one of the primary branches of biology . The term is derived from Ancient Greek ζῷον , zōion ('animal'), and λόγος , logos ('knowledge', 'study'). Although humans have always been interested in

4484-614: Is the subfield of biology that studies the evolutionary processes (natural selection, common descent, speciation) that produced the diversity of life on Earth. Evolutionary research is concerned with the origin and descent of species , as well as their change over time, and includes scientists from many taxonomically oriented disciplines. For example, it generally involves scientists who have special training in particular organisms such as mammalogy , ornithology , herpetology , or entomology , but use those organisms as systems to answer general questions about evolution. Evolutionary biology
