Revise the passage Darwin is best known for his Theory of Inheritance of Acquired Characteristics, first presented in 1801 (Darwin's first book dealing with natural selection was published in 1859):Based on these observations and inferences, Darwin concluded that these traits, called adaptations were the product of evolution by Acquired Traits, these traits made the members of the population who had them equally fit for survival. an organism could also change during their lifetime in order to adapt to its environment, those changes are passed on to its offspring. For example, darwin believed that if giraffes stretched their necks to reach food, Their offspring and later generations would inherit the resulting long necks.

Darwin is best known for his Theory of Inheritance of Acquired Characteristics, first presented in 1801 (Darwin's first book dealing with natural selection was published in 1859):Based on these observations and inferences, Darwin concluded that these traits, called adaptations were the product of evolution by Acquired Traits, these traits made the members of the population who had them equally fit for survival. an organism could also change during their lifetime in order to adapt to its environment, those changes are passed on to its offspring. For example, darwin believed that if giraffes stretched their necks to reach food, Their offspring and later generations would inherit the resulting long necks.
Darwin and Lamarck proposed theories explaining evolution.
Darwin proposed the theory of natural selection. According to him, variation possessed by organisms provided certain organisms the advantage of surviving and reproducing better than the others. Changes that occur in an organism over the lifetime are not responsible for the evolution of species. These features appear more with each generation. This led to the phrase "survival of the fittest". For example, according to Darwin's theory, longed necked giraffes would have a high survival rate since they can eat leaves from taller trees. As a result, more long-necked giraffes will be born and the entire population of giraffes will have long necks allowing them to survive better in the natural environment.
According to Lamarck, organisms change over their lifetime and these changes are passed onto the offspring and this leads to the evolution of species. For example, Lamarck believed that giraffes developed a long neck during their lifetime in order to reach the leaves of the taller trees. This is passed on to the next generation and this generation of giraffes will have a longer neck than the parental generation. Thus, the later generations of the giraffes will inherit the long necks from the parental generation.
