Life history theory ( LHT) is an analytical framework [ 1] designed to study the diversity of life history strategies used by different organisms throughout the world, as well as the causes and results of the variation in their life cycles. [ 2] It is a theory of biological evolution that seeks to explain aspects of organisms' anatomy and ...
Following the inception of Charles Darwin 's theory of natural selection in 1838, the development of Darwin's theory to explain the "mystery of mysteries" of how new species originated was his "prime hobby" in the background to his main occupation of publishing the scientific results of the Beagle voyage.

Learning styles. Learning styles refer to a range of theories that aim to account for differences in individuals' learning. [ 1] Although there is ample evidence that individuals express personal preferences on how they prefer to receive information, [ 2]: 108 few studies have found validity in using learning styles in education. [ 3]: 267 Many ...
Developmental systems theory ( DST) is an overarching theoretical perspective on biological development, heredity, and evolution. [ 1] It emphasizes the shared contributions of genes, environment, and epigenetic factors on developmental processes. DST, unlike conventional scientific theories, is not directly used to help make predictions for ...
Neo-Darwinism is generally used to describe any integration of Charles Darwin 's theory of evolution by natural selection with Gregor Mendel 's theory of genetics. It mostly refers to evolutionary theory from either 1895 (for the combinations of Darwin's and August Weismann 's theories of evolution) or 1942 ("modern synthesis"), but it can mean ...
