What do we learn from identification of individuals and populations?
From the identification of individuals and populations, we learn about the sharing of similarities among living organisms both horizontally and vertically. It reveals that all present day living organisms are related to each other and also to all organisms that ever lived on this earth.
Identification is a basic process of taxonomy that allows for correct description and nomenclature. These taxonomic studies are useful in agriculture, forestry, and industry for knowing our bio-resources and their diversity. Ultimately, this knowledge leads to cultural movements for the conservation of biodiversity.
Explanation
The answer is derived from the provided context which states that the 'biggest spin off' of taxonomic studies (which include identification) is the recognition of similarities among organisms and their relatedness. The context explicitly mentions that identification helps us understand that organisms are related to each other and to those that lived in the past. Additionally, the text highlights the practical utility of these studies in fields like agriculture and industry, and their role in biodiversity conservation.
