Definition of Lentigo
Lentigo: A type of freckle that is a small tan, brown, or black spot which tends to be darker than the usual (ephelis-type) freckle and which do not fade in the winter. This kind of spot is referred to as lentigo simplex. Although lentigines may be part of a genetic disorder, for the most part they are just isolated and unimportant spots. (The genetic disorder in which lentigines occur is called the LEOPARD syndrome.)
Lentigo is the Latin word for lentil. A lentigo looks like a lentil bean. The plural is lentigines.

Definition of Lamarckism
Lamarckism: The theory of acquired characteristics put forth by Jean-Baptiste P.A. Lamarck (1744-1829), a French botanist, zoologist and biological philosopher.
According to Lamarck, evolution occurs because organisms can inherit traits acquired by their ancestors. Giraffes can only survive by eating leaves high up on trees so they stretch their necks to reach the leaves and this stretching of the neck is passed on to later generations.
The basic tenet of Lamarckism has been rejected. Darwinism (the theory of the origin of species and the development of higher organisms from lower forms through natural selection, the survival of the fittest, and the evolution of humans from an ancestor common to himself and the apes) has prevailed, together with the principles of transmission genetics.
Lysenkoism was a 20th-century Soviet version of Lamarckism.
