Inheritance of acquired characters

Vedclass · Answer

(A) Lamarckism,proposed by Jean-Baptiste Lamarck,is primarily based on the theory of the 'Inheritance of Acquired Characters'.This principle suggests that organisms can pass on physical characteristics that they acquired during their lifetime to their offspring.For example,the long neck of a giraffe was explained as an acquired trait due to the continuous stretching of the neck to reach leaves on high branches,which was then inherited by subsequent generations.'Survival of the fittest' and 'Natural selection' are the core principles of Darwinism,not Lamarckism.
