Lamarkianism

In the theory of evolution, lamarkianism (named after Jean-Baptiste Lamarck 1744-1829) was the idea that an organism can pass down a trait to its young based on need and physical adaptation during the parent’s lifetime due to that need.  For example, it was proposed that the giraffe developed its long neck by stretching and this elongated neck was then passed down to its offspring.
