Darwinian and Lamarckian Theories of Evolution

There are many ideologies and arguments on how evolution and the present life came into existence. However, there are many theories brought forward, each with its own argument and point of view as well as strong points which purports the argument. The Darwinian and Lamarckian theories of evolution are the most popular evolutionary theories which consist of similarities and differences.

The evolutionary according to the theory of natural selection popularized by Darwin and Wallace also referred to as the Darwinian Theory, states that there exists variation in all living things and mutations happen within natural settings, and passed to the next generation of offspring. The environment is among the factors that cause mutations in that those organisms with stronger traits and characteristics survive than those with none or less of the characteristics. The natural selection happens across all organisms and only the best of the population survive.

The evolutionary according to the doctrine of acquired characteristics by Jean Lamarck on the other hand relies on the ideology that living organisms have the ability to pass certain characteristics that it deems importance to its offspring. Unlike the Darwinian theory which suggests that there are variations in offspring, this theory works by arguing that the characteristics passed down to future offspring are of high importance that the parent deems important and of high value to continue with future generations. This confirms that offspring and young ones in an organism have the behavioral tactics and traits acquired from their parents.

Both ideologies are similar in that they have a basis in which the theorists base their arguments on and therefore a basis in which modern scientists can look back from and have their arguments. They also have the belief that there is a relationship exists between living organisms and the present or future offspring.

The Darwinian theory of evolution explains better the biological evolution than the Lamarckian theory of evolution. This is because it explains that only the strongest and most relevant survive in a population of organisms. It is a form of population control where only the best will make it in life. It ensures that the weakest die and with that out of the way, the strongest and those with the right traits and characteristics can reproduce and replace the dead. The population still increases through reproduction. The other argues that characteristics passed down to offspring, which may then have weaker and negative traits passed down.

The Lamarckian theory can offer an explanation and give a light on the evolution of scientific ideas. This is because through the passing down of characteristics from the parents top the offspring. For instance, parents may have an idea on how to develop and invent things and may not quite grasp it. They may invent and miss something. However, their offspring may manage to develop and make the original ideology work. There are more resources available on all different offspring than parents have hence there is the possibility that there would be a better evolution of scientific idea.

The Lamarckian theory of evolution has implications on other theories developed after it and more specifically on the Popperian idea, which believes that the rich and available scientific knowhow and knowledge pools from a natural selection. On the other hand, the Kuhnian theory of evolution argues that science follows a stipulated path
