Neo-Lamarckism

Neo-Lamarckism The followers of Lamarck (Neo-Lamarckists) like Cope, Osborn, Packard and Spencer tried to explain Lamarck’s theory on a more scientific basis. They considered that adaptations are universal. Organisms acquire new structures due to their adaptations to the changed environmental conditions. They argued that external conditions stimulate the somatic cells to produce certain ‘secretions’ which reach the sex cells through the blood and bring about variations in the offspring.
