Vedclass · Answer

(A) Lamarckism,also known as the theory of inheritance of acquired characters,suggests that traits acquired by an organism during its lifetime are passed on to its offspring.August Weismann's experiment on mice,where he cut off their tails for many generations,showed that the offspring were still born with tails.Similarly,the fact that human females are not born with pierced earlobes,even though the practice has been performed for thousands of years,serves as a classic example that disproves Lamarck's theory,as acquired characters (like pierced ears) are not inherited.
