Darwinism beat Lamarckism in the study of how living things change over time. There are a few main reasons why Darwin's ideas are more accepted and backed by science.

1. How Traits Are Passed Down:

   • Darwin suggested that natural selection is what helps evolution happen. This means that animals and plants with helpful traits are more likely to survive and have babies. Those babies inherit the useful traits from their parents.
   • On the other hand, Lamarck thought that traits gained during an animal's life could be passed to its children. For example, he said giraffes have long necks because their ancestors stretched to reach high leaves. This idea is less convincing when we look at actual genetics.

2. Evidence to Support the Ideas:

   • Darwin’s theory gained support from studies in genetics and fossils. When scientists discovered DNA, it helped explain how traits are passed down, which backed up Darwin’s ideas about natural selection.
   • In contrast, Lamarck's theory didn’t have strong evidence. It couldn’t explain many things we see in nature, like how complex traits develop through genetic changes.

3. Making Predictions:

   • Darwinism can make predictions about how evolution works that we can test and see in real life. For example, when bacteria become resistant to antibiotics, it shows natural selection happening.

In summary, Darwinism is based on strong science, lots of evidence, and the ability to make predictions about living things over time. This is why it has become the main idea in understanding evolution.
