How does Larmark’s proposed method of evolution differ from Darwin’s?

Expert Solution

The theory of evolution proposed by Lamark and Darwin has a few similarities but has significant difference on which it is based.

Both the theories suggest evolution is a gradual process, complex species evolve from simple ones. But the difference between Lamark's and Darwins theories lies in the key factors that drive this evolution.

Lamark proposed that evolution is driven by inheriting acquired traits in a species, some traits in a species are enhanced by the need to survive in an environment.The environment plays a pivotal role in inducing change in an organism. A popular example is the giraffes long neck, induced by the environment enabling them to provide access to food.The offspring of the giraffes inturn had even longer necks.They inherited the these environmentally induced traits.

Darwin's theorised that evolution is driven by surival of the fittest, the changes in a species occuring irrespective of the need.Occurence of random mutations in a species over time helping them with survival. Competition within a species for food , mate, survival of the fittest has been the basis.For example, running faster to escape from predator animals.

How did Lamarck’s theory of evolution DIFFER from that of Darwin’s? Lamarck believed that Earth was old enough to provide a sufficient time scale for the process of evolution. Lamarck believed that the environment played a significant role. Lamarck believed that characteristics acquired during an organism’s lifetime could be passed on to the next generation. Lamarck believed that acquired character during an organism’s lifetime could not be passed on to the next generation.

Think about how the biological mechanisms of epigenetics differ from those of genetics (which is evolution, or gene mutation over many, many generations). Do epigenetics mutate the sequence of our DNA like evolution does? Do they take hundreds of generations to show up like evolution does? If evolution is the driving force behind genetics, what is the driving force behind epigenetics? Could we conclude that it's our environment?
