Darwin Vs Lamarck

Contrary to popular belief, Charles Darwin was actually not the first biologist to suggest that species rehabilitated over time into new more developed and advanced species. Darwin alongside Jean-Baptiste Lamarck and a few other naturalists eventually coined the concept of evolution by the end of the 1700s. For most of his life, Lamarck focused on his two proposed mechanisms, of which both were very successful in the science world. As species adapted to the environment and their surroundings, the nature of their species also began to progressively adapt and become more complex springing from simple to more complex beings. Lamarck also hypothesized the idea of spontaneous generations in which he theorized that new primeval life species essentially

Transgenerational epigenetic inheritance (TEI) is concept of epigenetic marks such as DNA methylation and histone modifications that can be used on DNA for the next generation and are also passed on throughout the gametes of further generations. Lamarck had been trying to find an answer to his question of inherited characteristics for much of his lifetime, arguably even before Darwin began to prepare his theory of evolution. The idea of transgenerational inheritance was described as Lamarck as survival characteristics that were developed and continuously used by species that could potentially be assimilated or developed in subsequent generations as well. A common example of the theory of inheritance can be seen in animals who must have longer bodies or more specifically longer necks in order to reach the tops of trees for their food supply. If the animal could progressively develop a response to environment and evolve so that they can successfully reach higher leaves, the trait was proved to be effective and this attribute would potentially be passed onto the next

Lamarckism did not show much significance in plant and animal studies but with bacteria, Lamarck had many breakthrough studies; remarkable enough to be associated with implications alongside human health. Some classes of bacteria are thought to have multiple forms and shape, making bacteria pleomorphic. Through research we know that some classes of bacteria inevitably produce a protein, this is known as an inducible enzyme. For example, a microbial cell can produce the sugar-digesting enzyme beta-galactosidase with the existence of its lactose substrate when placed in a culture medium. When this occurs, the cell divides though the process of fission and produces two inherently identical cells, one of which gets relocated to the medium that is lactose free; the continued division of the bacterial cell until degradation is called perdurance. Perdurance happens when the phenotypic expression of a gene is unaffected even after the gene has been deleted or inactivated due to the prolonged nature of the cell life. Similar to transgenerational epigenetic traits in animals, perdurance can explain how and why the inheritance of a necessary trait in bacteria
