Explain how scientific investigations that preceded lamarck contribution to the development of his theory of evolution?

Lamarck's theory proposed that the changes a species undergoes and passes on to its offspring are a result of its inner striving toward perfection or an adaptation fueled by necessity. An example of Lamarckian evolution would be a man and a woman developing significantly stronger upper arms as a result of their professions or sports activities, and then producing children that also possessed stronger upper arms. Modern research into genetics has discredited this major premise of Lamarck's evolutionary theory.
