Concept explainers
Briefly summarize Lamarck’s concept of the evolutionary process. What is wrong with this concept?
To summarize: The Lamarck’s cancept of process of evolution.
Introduction: Evolution refers to a process of changes that occur in the heritable characters of living organisms over a period of time, from generation to generation. The genetic variation occurs due to mutations, genetic drift, natural selection, and gene flow.
Explanation of Solution
The Lamarcks concept of evolutionary process states that the physical charecteristics acquired by a parent during their lifetime get transferred to their offspring.
To explain: The wrong with the Lamarck’s cancept of process of evolution.
Explanation of Solution
The Lamarcks concept of evolutionary process states that the physical charecteristics acquired by a parent during their lifetime get transferred to their offspring. But, the physical charecteristics do not get transferred to their offspring; only genetical changes in reproductive cells only get transferred.
