Lamarckism was proposed by Jean-Baptiste de Monet Lamarck in the year 1744-1829. This theory was based on the principle that all the physical changes occurring in an individual during its lifetime are inherited by its offspring. For eg., the development of an organ when used many times. This theory has been explained here.
Apr 12, 2021 · The name Lamarck is very well known in the teaching of biology, being associated with an early effort to explain evolution. Nevertheless, when evolution is taught in the classroom, the only Lamarckian ideas that stand out are related to the ‘inheritance of acquired characters’, invariably illustrated by the example of the lengthening of giraffes’ necks, as a way of contrasting Lamarckian ...

Though he was building on the work of his mentor, Count George-Louis Leclerc de Buffon, Jean-Baptiste Lamarck (1744-1829) is often credited with making the first large advance toward modern evolutionary theory because he was the first to propose a mechanism by which the gradual change of species might take place. Also, he extended the ...
In the early nineteenth century, Jean-Baptiste Lamarck published a book that detailed a mechanism for evolutionary change. We now refer to this mechanism as an inheritance of acquired characteristics by which the environment causes modifications in an individual, or offspring could use or disuse of a structure during its lifetime, and thus ...
In the early 19th century prior to Darwinism, Jean-Baptiste Lamarck (1744–1829) proposed his theory of the transmutation of species, the first fully formed theory of evolution. In 1858 Charles Darwin and Alfred Russel Wallace published a new evolutionary theory, explained in detail in Darwin's On the Origin of Species (1859). Darwin's theory ...
