Question

The main dictate(s) of Lamarck's theory is/are:

• A. Speciation
• B. Effects of use and disuse of organs
• C. Inheritance of acquired characteristics
• D. Survival of fittest

Answer 1

Answer: (B), (C)

Inheritance of acquired characteristics

Lamarck incorporated two main postulates in his theory of evolution. The first was use and disuse of organs according to which individuals lose characteristics that they do not require, over continuous disuse and develop characteristics that are useful. His second postulate was that these changes that are caused in the organism, due to use or disuse, are inherited by the next generation, and the offsprings are born with that change.
Speciation and survival of the fittest are Darwin's theory.
