Many of the things around us are being communicated with words. Words are the medium of communication and expression. They are what allows us to pass on the wisdom of one generation to the other. It allows us to communicate ideas. This is why humans change and evolve fatser than the most lethal of pathogen.
Darwin's theory of evolution postulates that the traits of a species is determined by genetic mutations(which is quite rare) and cannot be changed after birth. This evolution process takes place very slowly. You don't see a monkey giving birth to a human baby.
Lamarck's theory however, suggests that the traits of each species change according to their surroundings, and these enhanced traits get passed on to their offspring. The offspring evolve further and pass on their enhanced traits to the new generation and so on. This evolutionary process takes place very quickly as compared to Darwinian evolution. It was however proven untrue by a cruel and stupid experiment.
Both theories of evolution are concepts show nothing wrong or inconsistent when scrutinised. The Lamarckian theory was empirically disproven. This means to say that the Lamarckian theory may be used to explain something else, if there is sufficient empirical evidence.
I think that mankind evolve with Lamarckian evolution after the invention of language. Knowledge is power, and if people could teach their offspring what to avoid and what to eat, then these enhancements can be added into humans without the times spent in the painstakingly slow process of Darwinian evolution. Without any knowledge and tools, can one survive in the jungle? Unlikely. But if you release fish into the wild waters or a cockroach into jungle, they can survive. This is because their survival capabilities are encapsulated in their genome and they instinctively can survive. However, humans survive because of the ability to pass on advantages and knowledge from one generation to another. We survive because we evolve according to the Lamarckian theory, and not by the Darwinian theory.
There is not a great change in the genome from the victorian age till now, but our behaviour is different. I think it is mostly due to words. The way that we change is based on the information we receive. We evolve extremely fast when we compare ourselves to the other species. No other species adapt, evolve and prgress so fast.
