Biology is a branch of science that deals with living organisms and their vital processes Biology encompasses diverse fields, including botany, conservation, ecology, evolution, genetics, marine biology, medicine, microbiology, molecular biology, physiology, and zoology
- Biology Portal | Britannica
The field of biology is subdivided into separate branches for convenience of study, though all the subdivisions share basic principles Biology encompasses fields such as botany, genetics, marine biology, microbiology, molecular biology, and much more
- Biology - Evolution, Genetics, Classification | Britannica
Biology - Evolution, Genetics, Classification: There are moments in the history of all sciences when remarkable progress is made in relatively short periods of time Such leaps in knowledge result in great part from two factors: one is the presence of a creative mind—a mind sufficiently perceptive and original to discard hitherto accepted ideas and formulate new hypotheses; the second is the
- Biology - Aristotle, Organisms, Cells | Britannica
Biology - Aristotle, Organisms, Cells: Around the middle of the 4th century bce, ancient Greek science reached a climax with Aristotle, who was interested in all branches of knowledge, including biology Using his observations and theories, Aristotle was the first to attempt a system of animal classification, in which he contrasted animals containing blood with those that were bloodless The
- Reproduction | Definition, Examples, Types, Importance, Facts . . .
Reproduction, process by which organisms replicate themselves Reproduction is one of the most important concepts in biology: it means making a copy, a likeness, and thereby providing for the continued existence of species Learn more about the process of reproduction in this article
- Biology - Evolution, Natural Selection, Adaptation | Britannica
Biology - Evolution, Natural Selection, Adaptation: As knowledge of plant and animal forms accumulated during the 16th, 17th, and 18th centuries, a few biologists began to speculate about the ancestry of those organisms, though the prevailing view was that promulgated by Linnaeus—namely, the immutability of the species Among the early speculations voiced during the 18th century, the British
- Biology - Evolution, Genetics, Species | Britannica
Biology - Evolution, Genetics, Species: In his theory of natural selection, which is discussed in greater detail later, Charles Darwin suggested that “survival of the fittest” was the basis for organic evolution (the change of living things with time) Evolution itself is a biological phenomenon common to all living things, even though it has led to their differences Evidence to support
- Life | Definition, Origin, Evolution, Diversity, Facts | Britannica
Life, living matter and, as such, matter whose attributes include responsiveness, growth, metabolism, energy transformation, and reproduction Each individual is composed of one or more minimal living units, called cells, and is capable of transformation of compounds, growth, and participation in reproductive acts
- Life - Genetics, Evolution, Biology | Britannica
Life - Genetics, Evolution, Biology: All organisms on Earth, from the tiniest cell to the loftiest trees, display extraordinary powers They effortlessly perform complex transformations of organic molecules, exhibit elaborate behaviour patterns, and indefinitely construct from raw materials in the environment more or less identical copies of themselves How could systems of such staggering
