Question

Why was lamark’s theory disproved.​

Answer 1

Answer: It's because he proposed that acquired characteristics were inheritable. He highlighted in his theory that changes in plants or animals are adaptive in characteristics, which makes more scientists opposing his theory of evolution since it's impossible and it makes no sense.

For example, according to Lamarck, the girrafe's neck in the past is not long. Time flies and the number of animals in the forest increased and many predators scrimmage in the forest. Due to the lack of food, the girrafe tried another way to provide a food for itself. The girrafe stretches its neck to browse higher trees, the continuition of the habit over a long period of time gradually extend the limbs of their neck.
