History of biology

See related Biology

A history of biology does not constitute an evaluation of the veracity of biological ideas. It does not attempt to give answers to the fundamental questions in biology, or even to define those questions. It tries to recognize the myriad ideas of individuals curious about the myriad aspects of the living world, including those individuals whose ideas have all but disappeared from the everyday knowledge base. It tries to follow the path of human curiosity about workings of living things. We will try to heed the words of the editor of the Journal of the History of Biology:

While hard data will always serve as the basis of history, the simple narrative is no longer acceptable, particularly when dealing with the emergence of ideas. The best history will be characterized by penetrating and critical analysis of changing concepts and altered methods of experiment and observation. Biology, in particular, must be studied in terms of its relationships with the other sciences and with the intellectual currents of its day.

Prehistory

An unrecorded history of biology began when prehistoric human foragers first started to accumulate information about the behavior of plants and animals in their environment, which they did presumably for its importance in helping them acquire food for subsistence.

Homo sapiens, emerged nearly 200,000 years ago, exhibiting unprecedented cognitive abilities. They could discriminate cause and effect widely in nature, they could speak and thus share knowledge and cooperatively accumulate it to pass it down the generations, and they could make tools — all prerequisites for a successful study of food sources for immediate practical purposes. Living as hunter-gatherers, they learned the details of the behavior of animals and plants as they needed to subsist and thrive in the wild. How they managed to organize and teach their knowledge we can only speculate. Reports of direct observations of 19th and 20th century hunter-gatherer societies, whose lifestyle resembled them give some appreciation of the likely expertise important for survival required of our hunter-gatherer ancestors.

Beginning approximately 10,000 years ago, self-expanding biological knowledge in the Middle East plausibly played a major role in evolving productivity in agriculture and the domestication of wild animals such as dogs and sheep. Some biologists extrapolate backwards in time from historic processes to speculate on the knowledge-based aspects of the developments in cultivation and domestication for human benefit by prehistoric agriculturalists. Harold Morowitz, Yale Professor of Biology and Natural Philosophy, views prehistoric agriculturalists as ‘natural’ biologists and selectionists:

Domestication provides for rapid evolution of the species employed. A selection for fitness was imposed by the domesticators. Thus, large seeds, fleshy fruits, and other desirable properties were selected in choosing for planting. In time this had its genetic consequences, and new strains emerged. Similarly, in animal populations selection for docility or size or some other feature would alter a species....Animal domestication might have been preceded by hunter-gatherers who captured orphaned young animals and raised them in captivity. This would have provided information necessary for large-scale animal domestication. In a very real sense, agriculture is a knowledge-driven activity. Knowledge must be communicated by language and must eventually be stored by writing.

Farming techniques were invented possibly independently in at least seven parts of the world, including the Middle East, Asia, Sub-Sahara Africa, and the Western Hemisphere.

Beginnings of ancient biology

Aristotle, the founding father of the science of biology

Aristotle gave some thought to the question, "what is life?". He thought that a living thing existed in 'potentiality' in the seed or semen, that environment factors initiated the realization of that potential, and that that potential included the "nutritive power" needed for it to grow into the living thing. Corresponding to that triad of suppositions by Aristotle, though it takes more than semen to generate a human, modern biologists teach that the 'potentiality' of the human exists as molecules in the semen and ovum, that the fluid composition in the oviduct, where the the sperm and ovum meet, enables their fusion — the fertilization process that starts the life form — and that the zygote (the first cell of the human) has within itself the wherewithal to utilize its own organization to develop itself into a multi-cellular individual human.

Aristotle developed a coherent vision of the nature of living thing. His four components of the causes of complex natural things, anticipates the somewhat more refined modern systems biology approach to the question of life, wherein a living thing comprises:

• A collection of organic and inorganic parts (molecules and ions; cells, organelles, organs and organisms) — Aristotle’s 'material' cause, the parts that make up the living thing; Aristotle only recognized some of the organs;
• Parts relating to each other to form structures (e.g., networks), how they interact with each other (e.g., network dynamics), and how the structures interact with each other in a coordinated dynamic and hierarchical manner — Aristotle’s 'formal' (form-like) cause, the form the living thing takes on from the parts; Aristotle thought in terms of sculpture;
• Parts and structures dynamically coordinated (e.g., gene expression; self-organization) — Aristotle’s 'efficient' (effect-producing) cause, how the living thing gets produced into its form; the moving force; Aristotle thought about something putting it together;
• How the living system as-a-whole functions and behaves, and the properties that characterize it (e.g., reproduction; locomotion; cognition) — Aristotle’s 'final' cause, its function; Aristotle thought in terms of the thing's 'purpose' or 'goal';

Modern biologists go down the road started as a path by Aristotle, who would have been delighted to know he asked the right questions during his pathbreaking studies, even if he did not know how to get the right answers. Unfortunately, the larger fraction of his writings have disappeared, so we cannot know the full breadth of Aristotle's curiosity and biological adumbrations. What he did leave had a major effect on Western thought for centuries.
