How did Lamarack's ideas differ from Darwin's?

Answer 1

Lamarck's ideas differed from Darwin's primarily in their mechanisms of evolution. Lamarck proposed that organisms could acquire traits during their lifetime and pass these traits to their offspring, a concept known as "inheritance of acquired characteristics." In contrast, Darwin introduced the theory of natural selection, which posits that individuals with advantageous traits are more likely to survive and reproduce, leading to gradual changes in populations over time. While both recognized evolution as a process, their explanations of how it occurs were fundamentally different.
