I.1.2 Relationships with other disciplines: Life Sciences

The life sciences or biological sciences comprise the branches of science that involve the scientific study of life and organisms – such as microorganisms, plants, and animals including human beings.

Life science is one of the two major branches of natural science. Biology is the natural science that studies life and living organisms, with the other life sciences being its sub-disciplines. It is divided into-

  1. zoology is the study of animals
  2. botany is the study of plants.

some of  the sub-braches are-

  • Anatomy – study of form and function, in plants, animals, and other organisms, or specifically in humans.
  • Biotechnology – study of combination of both the living organism and technology.
  • Biochemistry – study of the chemical reactions required for life to exist and function, usually a focus on the cellular level.
  • Biolinguistics – study of the biology and evolution of language.
  • Biomechanics – the study of the mechanics of living beings.
  • Biophysics – study of biological processes by applying the theories and methods that
  • Cell biology – study of the cell as a complete unit, and the molecular and chemical interactions that occur within a living cell. Also known as cytology
  • Developmental biology – study of the processes through which an organism forms, from zygote to full structure
  • Ecology – study of the interactions of living organisms with one another and with the non-living elements of their environment
  • Ethology – the study of behavior
  • Evolutionary biology – study of the origin and descent of species over time
  • Histology – the study of tissues
  • Immunology – the study of the immune system
  • Microbiology – study of microscopic organisms (microorganisms) and their interactions with other living organisms
  • Molecular biology – study of biology and biological functions at the molecular level, some cross over with biochemistry, genetics and microbiology
  • Physiology – study of the functioning of living organisms and the organs and parts of living organisms
  • Population biology – study of groups of conspecific organisms
  • Toxicology – the nature, effects, and detection of poisons
  1. Anthropology and Botany
  2. Anthropology and Zoology- click here
Anthropology Life-sciences
 Scope is universal, it deals with biology (which is matter and life) and learned behavior of humans.

Whole-science. It examines biology, culture and society together.

Anthropology is a newer field of study.

Life-sciences deal with biology (which is matter and life) and instinctual behavior of organisms.

Part-sciences. It examines biological system
and biological behavior together.

Life-Sciences are older than anthropology.

Only some life-cycle processes are amenable to observation. All life-cycle processes are amenable to observation.
Lesser scope for validity and reliability of data. Greater scope for validity and reliability of data.
 Uses experiments to a limited extent. Uses controlled experiments to a great extent.
