The key point in Lamarck's view of organic evolution and basic principle is

Options

A. origin of species
B. inheritance of acquired characters
C. over population
D. natural selection

Answer

**Step-by-Step Text Solution:**

1. **Introduction to Lamarck's Theory**: Begin by understanding that Jean-Baptiste Lamarck was a French biologist who proposed a theory of evolution that was different from Darwin's natural selection.

2. **Key Concept**: The central idea of Lamarck's theory is the "inheritance of acquired characteristics." This means that traits or characteristics that an organism develops during its lifetime can be passed on to its offspring.

3. **Explanation of Acquired Characteristics**: According to Lamarck, if an organism changes during its life in response to its environment, these changes can be inherited by the next generation. For example, if a giraffe stretches its neck to reach higher leaves, this acquired longer neck would be passed down to its offspring.

4. **Basic Principle**: The basic principle of Lamarck's view of organic evolution is thus the inheritance of acquired characteristics. This principle suggests that evolution occurs as organisms adapt to their environments and these adaptations are then inherited.

5. **Comparison with Other Theories**: It is important to note that Lamarck's ideas were later challenged by Charles Darwin's theory of natural selection, which emphasizes that only genetic traits that provide a survival advantage are passed on.

6. **Conclusion**: In summary, the key point in Lamarck's view of organic evolution is the concept of inheritance of acquired characteristics, which he believed was the mechanism driving evolution.
