Difference between Darwin and Lamarck

Charles Darwin and Jean-Baptiste Lamarck are two of the most famous naturalists in history, but they had different ideas about how evolution works. Darwin believed that random genetic mutations caused changes in organisms over time, while Lamarck believed that environmental factors could cause an organism to adapt and pass those adaptations on to its offspring.

What is Darwin?

Darwin’s theory of evolution is one of the most important scientific theories of all time. It states that all plants and animals have descended from common ancestors, and that the process of evolution has led to the diversification of life on Earth. The theory was first proposed by Darwin in his 1859 book On the Origin of Species, and it has since been supported by a wealth of evidence from many different fields of science. Today, Darwin’s theory is widely accepted by the scientific community, and it continues to play a central role in our understanding of the natural world.

What is Lamarck?

Lamarck theory, also known as Lamarckism, is the idea that an organism can pass on traits that it acquired during its lifetime to its offspring. Lamarck proposed this theory in the early 19th century, and it remained an influential explanation for the inheritance of acquired characteristics until the rise of Darwin’s theory of evolution by natural selection in the mid-19th century. Lamarckian inheritance has since been discounted by modern science, but Lamarck’s ideas continue to be studied for their historical importance.

Difference between Darwin and Lamarck

While Darwin and Lamarck both had theories about evolution, there are a few key ways in which their ideas differ. For Darwin, the driving force behind evolution was natural selection or the process by which organisms that are better suited to their environment survive and reproduce. Lamarck, on the other hand, believed that evolution was driven by the acquisition of new characteristics during an organism’s lifetime. He theorized that these acquired traits could be passed down to future generations. Furthermore, while Darwin’s theory is supported by extensive scientific evidence, Lamarck’s theory is not backed up by many scientific data. As a result, Darwin’s theory is generally accepted by the scientific community, while Lamarck’s theory is not. Despite their differences, however, both Darwin and Lamarck made important contributions to our understanding of evolution.


The difference between Darwin and Lamarck is an important one, but it can be hard to understand without a solid background in biology. We hope this article has given you a better understanding of the two theories and how they differ.
