In 1889, biologist hugo de vries was inspired by darwin's work and developed the principle of intracellular pangenesis to explain inheritance by suggesting that traits are carried by tiny particles he called pangens in honor of pangenesis. Gone was the requirement that these pangens would change in response to use/disuse and injury factors that darwin had suggested, but the intellectual link between darwin and early modern principles of inheritance is clear.

In his theory of “intracellular pangenesis”, de vries coined the new term “pangen”: “to the smallest particles, of which each represents one hereditary characteristic, i shall give a new name and call them pangens, because with the designation ‘gemmule’ is associated the idea of a transportation through the whole organism” (de vries, 1910).
Pangenesis definition is - a disproven hypothetical mechanism of heredity in which the cells throw off particles that collect in the reproductive products or in buds so that the egg or bud contains particles from all parts of the parent.

In 1889, de vries published his book intracellular pangenesis, in which, based on a modified version of charles darwin's theory of pangenesis of 1868, he postulated that different characters have different hereditary carriers. He specifically postulated that inheritance of specific traits in organisms comes in particles.
His best-known books are intracellular pangenesis, 1889, the mutation he went on to the university of heidelberg where he worked with the german plant.

Specifically, in 1889, hugo de vries published his book intracellular pangenesis, in which he postulated that different characters have individual hereditary carriers and that inheritance of specific traits in organisms comes in particles. De vries called these units pangenes (pangens in german), after darwin's 1868 pangenesis theory.
Sep 1, 2007 indeed, darwin also linked the cause of some variation with changes in a modern version of darwin's pangenesis is the 'somatic selection'.
De vries in 1889, suggested that hereditary instincts are caused by the presence of material particles (pangens) in living protoplasm. In contrast to darwin, de vries denied that pangens were transferred to the sex cells; he believed that each cell nucleus from its very inception contains all the pangens distinctive to a given individual.
De vries propounded the intracellular pangenesis theory in 1889, a modified theory of pangenesis. According to de vries, gemmules cannot transfer from body cells to sexual cells. De vries argued that gemmules could only move between the nucleus and the cytoplasm inside a single cell, so his theory was called intracellular pangenesis theory. To distinguish between his theory and darwin's, de vries used the term pangene to replace the term gemmules for the unit of hereditary materials.

Pangenesis was charles darwin's hypothetical mechanism for heredity, in which he proposed that each part of the body continually emitted its own type of small organic particles called gemmules that aggregated in the gonads, contributing heritable information to the gametes.
New adaptations would be successively diluted with each generation of darwin's hypothesis for inheritance, pangenesis, synthesized some earlier concepts of inheritance which de vries described in his intracellular pangenesis.
