In this essay I am going to compare the theories of Charles Darwin and Jean-Baptiste Lamarck.

Charles Darwin was a British Scientist who lived between 1809-1882. He laid down the foundation of modern evolutionary theory with his concept of the development of life through the slow working process of natural selection.

Darwin started to make notes about this theory in 1836 and in 1838 he had arrived at a sketch of a theory of evolution through natural selection. It was not until 1858 that his theory was first published in a paper. Darwin's theory is that as plants or animals spread to new areas, or as the conditions change different variations would be favoured in different places. This would mean these

Jean-Baptiste Lamarck was a Frenchman who lived between 1744 and 1829. He claimed that changes in a species are brought about by environmental pressures-such as changes in the food or weather patterns. The changes that take place in an individual over a lifetime are passed down to its offspring.

variations would spread through the populations of the plants or animals. Over time this would finally lead to a development of new species. This theory was explained in the book 'The Origin of Species', which describes his studies on the Galapagos Islands in the Pacific Ocean. He noticed that the species on the islands varied slightly from each island and were adapted to local conditions. The reaction to this theory was immediate. Biologists argued that Darwin could not prove his hypothesis. Othe
