What Was Missing in Darwin’s Theory of Evolution?

Darwin’s theory of evolution is one of the most significant scientific theories that has ever been proposed. However, like any other theory, it has its limitations.

Even though Darwin made some groundbreaking discoveries about the natural world, there are some things that were missing in his theory of evolution. In this article, we will explore what was missing in Darwin’s theory of evolution.


Charles Darwin is known for his work on the theory of natural selection. He proposed that species evolve over time through a process called natural selection.

According to him, organisms with advantageous traits are more likely to survive and reproduce than those without them. Over time, these advantageous traits become more common in a population, leading to the evolution of new species.

What Was Missing?

Even though Darwin’s theory of evolution was revolutionary at the time, it had some limitations. Here are some things that were missing from his theory:

1. The Mechanism for Inheritance

Darwin did not understand how traits were inherited from one generation to another. It wasn’t until later that Gregor Mendel discovered the laws of inheritance and helped scientists understand how traits are passed down from parents to offspring.

2. The Role of Genetic Variation

Darwin did not fully appreciate the role of genetic variation in driving evolution. It wasn’t until scientists discovered DNA and started studying genetics that they realized how important genetic variation is for natural selection to occur.

3. The Importance of Chance Events

Darwin’s theory focused on natural selection as the driving force behind evolution but did not fully appreciate the importance of chance events such as genetic drift and gene flow.

4. The Evolutionary History of Life

Finally, Darwin’s theory did not provide a comprehensive explanation for the evolutionary history of life on Earth.


In conclusion, Darwin’s theory of evolution was a groundbreaking discovery that changed the way we view the natural world. However, it had some limitations, and there were some things missing from his theory.

Over time, scientists have built on Darwin’s work and have helped us understand more about how evolution works. Today, we have a much better understanding of how traits are inherited, the importance of genetic variation, the role of chance events in evolution, and the evolutionary history of life on Earth.
