Biology has a history of about 4 billion years in the history of the earth. About 6.5438+0.5 million species of organisms have become extinct, and some of their remains are preserved in the strata to form fossils.
Paleontology specializes in studying organisms in geological history through fossils. Early paleontology mainly focused on the classification and description of fossils. Later, various branches of biology were introduced into paleontology, resulting in branches of paleoecology and paleogeography. It has been suggested that paleontology, which was originally limited to the classification and description of fossils, should be replaced by paleontology in a broad sense.
There are so many groups of organisms that a special subject is needed to study the division of groups. This subject is taxonomy. The classification in Linnaeus period is guided by the theory of species invariance, and it is only classified according to some distinguishable characteristics, which is called artificial classification. Modern classification is guided by evolution.
According to the evolutionary distance of species, it is called natural classification. Modern taxonomy not only compares the morphological structure, but also absorbs the achievements of biochemistry and molecular biology at the molecular level, thus revealing the evolutionary relationship of organisms more deeply. Modern taxonomy can be defined as a science that studies the systematic classification of organisms and the evolutionary relationship between organisms.
Many branches of biology are divided according to the properties, characteristics or life processes of life movements.
