Vavilov's 1924 scheme suggested that plants were domesticated in China, Hindustan, Central Asia, Asia Minor, Mediterranean, Abyssinia, Central and South America. A Vavilov center or center of origin is a geographical area where a group of organisms, either domesticated or wild, first developed its distinctive properties. [1]
Some foods have always been common in every continent, such as many seafood and plants. Examples of these are honey, ants, mussels, crabs and coconuts. Nikolai Vavilov initially identified the centers of origin for eight crop plants, subdividing them further into twelve groups in 1935. [1]
Centres of Plant Diversity (CPD) was established in 1998 as a joint classification initiative between the World Wildlife Fund (WWF) and the International Union for Conservation of Nature intended to identify the areas in the world that are of the highest conservation value in terms of protecting the highest number of plant species.

This map shows the sites of domestication for a number of crop plants. Places, where crops were initially domesticated, are called centers of origin. This is a list of plants that have been domesticated by humans. The list includes individual plant species identified by their common names as well as larger formal and informal botanical ...
Land plants evolved from a group of freshwater green algae, perhaps as early as 850 mya, [3] but algae-like plants might have evolved as early as 1 billion years ago. [2] The closest living relatives of land plants are the charophytes, specifically Charales; if modern Charales are similar to the distant ancestors they share with land plants, this means that the land plants evolved from a ...
A distinction can be made between botanical science in a pure sense, as the study of plants themselves, and botany as applied science, which studies the human use of plants. Early natural history divided pure botany into three main streams morphology-classification, anatomy and physiology – that is, external form, internal structure, and ...
Botany is a natural science concerned with the study of plants.The main branches of botany (also referred to as "plant science") are commonly divided into three groups: core topics, concerned with the study of the fundamental natural phenomena and processes of plant life, the classification and description of plant diversity; applied topics which study the ways in which plants may be used for ...
A Centre of Endemism is an area in which the ranges of restricted-range species overlap, [1] or a localised area which has a high occurrence of endemics. [2] Centres of endemism may overlap with biodiversity hotspots which are biogeographic regions characterized both by high levels of plant endemism and by serious levels of habitat loss.
