In biology, evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms ' observable traits .
Karl Pearson. Mendelian inheritance was rediscovered in 1900. However, there were differences of opinion as to the variation that natural selection acted upon. The biometric school, led by Karl Pearson followed Charles Darwin's idea that small differences were important for evolution.
Theistic evolution, the belief that God directly guided evolution [b] Neo-Lamarckism, the idea that evolution was driven by the inheritance of characteristics acquired during the life of the organism; Orthogenesis, the belief that organisms were affected by internal forces or laws of development that drove evolution in particular directions
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.

Jeffreys was studying DNA variation and the evolution of gene families in order to understand disease causing genes. [57] In an attempt to develop a process to isolate many mini-satellites at once using chemical probes, Jeffreys took x-ray films of the DNA for examination and noticed that mini-satellite regions differ greatly from one person to ...
The development and spread of antibiotic resistant bacteria provides evidence that evolution due to natural selection is an ongoing process in the natural world. Natural selection is ubiquitous in all research pertaining to evolution, taking note of the fact that all of the following examples in each section of the article document the process.
Paleoanthropology – the study of fossil evidence for human evolution, mainly using remains from extinct hominin and other primate species to determine the morphological and behavioral changes in the human lineage, as well as the environment in which human evolution occurred. Paleobotany – study of fossil plants.
