What is the comparison between Lamarck's and Darwin's ideas about how evolution takes place?

Lamarck's theory of evolution proposed that organisms could acquire traits during their lifetime and pass those traits to their offspring, a process often summarized as "inheritance of acquired characteristics." In contrast, Darwin's natural selection posits that variations among individuals in a population arise randomly, and those with advantageous traits are more likely to survive and reproduce, thus passing those traits to the next generation. While Lamarck emphasized the role of individual effort in adaptation, Darwin highlighted the importance of environmental pressures and random genetic variation as driving forces in evolution. Ultimately, Darwin's theory is more widely accepted and supported by genetic evidence.
