Ideas About Biology

Animal Biology, publishes high quality papers and focuses on integration of the various disciplines within the broad field of zoology. Cell theory states that the cell is the fundamental unit of life , that all living things are composed of one or more cells, and that all cells arise from pre-existing cells through cell division In multicellular organisms , every cell in the organism’s body derives ultimately from a single cell in a fertilized egg The cell is also considered to be the basic unit in many pathological processes.

Biology as a separate science was developed in the nineteenth century, as scientists discovered that organisms shared fundamental characteristics. Microbiology is made up of several sub-disciplines, including: bacteriology (the study of bacteria), mycology (the study of fungi), phycology (the study of algae), parasitology (the study of parasites), and virology (the study of viruses, and how they function inside cells) 1. These broad areas encompass a number of specific fields.

Evolutionary biology is partly based on paleontology , which uses the fossil record to answer questions about the mode and tempo of evolution, 57 and partly on the developments in areas such as population genetics 58 In the 1980s, developmental biology re-entered evolutionary biology after its initial exclusion from the modern synthesis through the study of evolutionary developmental biology 59 Phylogenetics , systematics , and taxonomy are related fields often considered part of evolutionary biology.

Graduate students from Cristescu Lab collecting environmental DNA at the Gault Nature Reserve, Mount Saint Hilaire. Biology: A natural science concerned with the study of life and living organisms. The branch of science which deals with the study of cells and their organelles. The College of Science Biology program provides students with a broad understanding of the organization and processes of life, from molecules and cells through tissues and organs, to populations, ecosystems, and evolution.

You can specialise in the strands of biology that interest you most, such as microbiology and biotechnology, cell and molecular biology, or ecology and evolution. On this module you’ll attend lectures, practical classes and workshops, supervised time in a studio or workshop and take part in guided independent study. The Bell Lab is currently extending laboratory investigations of experimental evolution to field scales at the Gault Nature Reserve.
