What is the primary mechanism that Darwin introduced to explain evolution? Natural selection Selective breeding Genetic mutation Environmenta adaptation

## Step 1<br />Charles Darwin is a renowned biologist who introduced the concept of evolution. His theory of evolution is based on the mechanism of natural selection.<br /><br />## Step 2<br />Natural selection is a process where organisms that are better adapted to their environment tend to survive and produce more offspring. This process leads to the evolution of species over time.<br /><br />## Step 3<br />The other options, such as selective breeding, genetic mutation, and environmental adaptation, are not the primary mechanisms that Darwin introduced to explain evolution.
