3- LABORATORY WORK.
Topic: Type - structure and methods of its formation
Purpose: To acquaint students with Darwin's views on the criteria of species, polytypic species and the emergence of species, and modern theories.
General information: Tour 'total morfofiziologik, genetic features free interlined, the seas, the nature of the next generation of a certain shape and in a few populations in the range of the sum of individuals. Currently, 2.5 million species of plants, 500 thousand. The first round of the term used by Aristotle. This term the full decision find K. Linney name. Ch.Darvin recognition of the existence of species in real time, dynamic, round about the materialist doctrine. According to this doctrine, tour the historic event, it will develop, improve living conditions of the level, and then change or disappear as a result of changes, new forms. It should be noted that live a certain level, which is a separate step in the evolution of the matter. He is the beginning part of the population mikroevolyutsiya as a result of self-important morphological, physiological, biochemical, genetic, environmental, and other types of Ethology features distinct taxonomic units.
The main criteria of a species : The set of certain characteristics that distinguish one species from another is called the criteria of the species. Currently, the species is distinguished by 4 main criteria : 1) Morphological, 2) Physiological-biochemical , 3) Genetic , 4) Ecological-geographical
Morphological criterion is an early criterion of a species. The morphological criterion involves the analysis of external and internal structural features. The morphological criterion is a relative criterion that does not fully elucidate the biological essence of the species. The limitation of the morphological criterion can be seen in the figurative round. For example; 6 figurative types of malaria mosquitoes are known. Some of these species feed on human blood, some have asked for the blood of domestic animals, some have laid eggs in fresh water, others have multiplied in salt water, and so on.
