Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.

Evolution Theories (in Hindi)

The scientific theory of evolution by natural selection was proposed by Charles Darwin and Alfred Russel Wallace in the mid-19th century and was set out in detail in Darwin's book On the Origin of Species (1859).

Lamarkism and Darvinism (in Hindi)

The remains or traces of organisms from a past geologic age embedded in rocks by natural processes are called fossils. They are extremely important for understanding theevolutionary history of life on Earth, as they provide direct evidence of evolution and detailed information on the ancestry of organisms.

Evidence of Evolution (in Hindi)

Evolution is the process of heritable change in populations of organisms over multiple generations. Evolutionary biology is the study of this process, which can occur through mechanisms including natural selection, sexual selection and genetic drift.

Course Overview

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Variation exists within all populations of organisms.

Natural Selection (in Hindi)

Evolution over time can follow several different patterns. Factors such as environment and predation pressures can have different effects on the ways in which species exposed to them evolve. shows the three main types of evolution: divergent, convergent, and parallel evolution.

Pattern of Evolution

Speciation is the evolutionary process by which populations evolve to become distinct species. The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages.

Species and Speciation.

History of Evolution. ... It was proposed by Charles Darwin in On the Origin of Species in 1859 and, independently, by Alfred Wallace in 1858—although Wallace, unlike Darwin, said the human soul is not the product of evolution.

Molecular phylogenetics is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominately in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved.

Molecular Phylogeny

A major goal of researchers studying the evolution of behavior is to link mutations to specific changes in complex behavioral traits . Behavioral evolution may involve changes in sensory systems, in the brain or even anatomical changes in the structures used to carry out a behavior.

Behavioural Evolution: Altruism

In evolutionary biology, inclusive fitness is one of two metrics of evolutionary success as defined by W. D. Hamilton in 1964. Inclusive fitness is the number of offspring equivalents that an individual rears, rescues or otherwise supports through its behaviour (regardless of who begets them).

Inclusive fitness and Hamilton's rule

Kin selection is the evolutionary strategy that favours the reproductive success of an organism's relatives, even at a cost to the organism's own survival and reproduction. Kin altruism can look like altruistic behaviour whose evolution is driven by kin selection.
