Darwin’s theory of natural selection and modern genetics both help us understand how species change over time. However, they look at different parts of this process. Let’s break down the main differences:
Darwin’s Theory: Charles Darwin said that natural selection is the main driver of evolution. He noticed that animals or plants with helpful traits are more likely to survive and reproduce. For example, a faster rabbit has a better chance of escaping from predators than a slower one.
Modern Genetics: This area focuses on genetic variation. It tells us that changes in the DNA, which is the genetic material, can lead to new traits. For instance, a mutation might allow a plant to create seeds that can fight off diseases better.
Darwin’s Viewpoint: Back in his time, Darwin didn’t know about genes. He could only guess how traits were handed down through different generations.
Genetic Science Today: Now we understand that traits come from genes made up of DNA. This knowledge is key to figuring out how traits can change over time, especially when genetic information mixes during reproduction.
In Darwin’s Era: The evidence he had mostly came from watching nature and studying fossil records.
Today’s Methods: Now, we use advanced tools like DNA sequencing. This helps us see how different species are related and gives us a clearer idea of how evolution works.
Together, these insights help us better understand the fascinating process of evolution!
