Multiple Choice

Which of the following statements best describes the difference between Jean-Baptiste Lamarck's and Charles Darwin's theories of evolution?

Lamarck believed in the inheritance of acquired characteristics, while Darwin proposed natural selection as the mechanism of evolution.

Darwin suggested that species evolve through use and disuse, while Lamarck emphasized survival of the fittest.

Lamarck and Darwin both agreed that evolution occurs through random genetic drift.

Lamarck's theory was based on genetic mutations, whereas Darwin focused on the role of environmental changes.

Verified step by step guidance

Identify the key components of Lamarck's theory: Lamarck believed in the inheritance of acquired characteristics, meaning that traits developed during an organism's lifetime could be passed on to its offspring.

Identify the key components of Darwin's theory: Darwin proposed natural selection as the mechanism of evolution, where organisms better adapted to their environment tend to survive and produce more offspring.

Compare the two theories: Lamarck's theory focuses on the idea that changes acquired during an organism's life can be inherited, while Darwin's theory emphasizes the role of natural selection in evolution.

Evaluate the options given in the problem: Determine which option correctly contrasts Lamarck's and Darwin's theories based on the identified key components.

Select the correct statement: Choose the option that accurately describes the difference between Lamarck's belief in acquired characteristics and Darwin's natural selection mechanism.
