Lamarckism (also known as Larmarkianism) is a school of evolutionary thought proposed by French biologist Jean-Baptiste Lamarck (Jean-Baptiste Pierre Antoine de Monet, Chevalier de Lamarck).[1]

This was one of the first theories that tried to explain the diversity of life based on naturalistic forces; as a scientific theory, it made predictions, and the failure to make accurate predictions make it a falsified scientific theory,[2]

Lamarck proposed that organisms' efforts to adapt to the environment can be accumulated and passed on to their offspring. Species evolved when traits acquired during life were passed from one generation to the next. For example, the ancestor of the giraffe was a short-necked herbivor, whose ancestors slowly forced their necks to grow to reach higher and higher trees.[1]

This is called, in biology, inheritance of acquired characteristics.

In his book The Origin of Species, Darwin spoke favorably of the Lamarckian theory of evolution. However, since the publication of Darwin's theory of natural selection and because of the lack of evidence for Lamarckian evolution in macrobiology, most biologists today favor an update of the Darwinian theory of evolution as the explanation for how human was evolved.

Despite all proofs and evidences against Lamarckianism, this theory became the official scientific theory in the Soviet Union, sponsored by Russian agronomist Trofim Denisovitch Lisenko, during the reigns of Stalin and Khruchtchev.[3][4]

Recent uptick of Lamarckism school of evolutionary thought

As can be seen below, there has been an uptick in macroevolutionary Lamarckism pseudoscience due to observed microevolutionary processes/changes seen in organisms related to Lamarckism:

However, due to intellectual inertia, the evolutionist indoctrination of students into Neo-Darwinism (also called the Modern evolutionary synthesis) and people's natural tendency to resist change, the neo-darwinian school of evolutionary thought is still dominant within the evolutionary biology community (see also: Paradigm shift). The weight of evidence still supports the biblical creation model (see also: Creation science). See also: Atheist indoctrination
