Consider the following statements regarding the laws of evolution from Lamarck's thesis and choose the correct answer:
1. The internal forces of life tend to increase the size of an organism not only as a whole but in every part as well
2. Each organ or part is the outcome of the new movement which in turn is initiated by a new and continuous need or want
3. All that has been acquired by an individual organism during its lifetime is transmitted by heredity to its offsprings in the next generation
