When we explore evolution, two old theories often come up: Darwinism and Lamarckism. Both try to explain how species change over time, but they have really different ideas. Let’s break down their main differences in a simple way.
Darwinism: This idea, created by Charles Darwin, says natural selection is the main way evolution works. It means that living things compete for limited resources, like food and space. The ones with helpful traits are more likely to survive and have babies. Over time, these traits become more common. It’s like the phrase “survival of the fittest”!
Lamarckism: Jean-Baptiste Lamarck had a different view. He believed in the idea that creatures could change during their lives and pass those changes to their kids. For example, if a giraffe stretched its neck to eat higher leaves, that longer neck could be given to its offspring.
Darwinism: This theory thinks of evolution as a slow and steady process that happens over a lot of generations. Changes build up gradually over a long time to create major changes.
Lamarckism: Lamarck’s theory suggests that changes can happen quickly. He believed that traits could appear and be passed down in just one generation, which doesn’t fit with what we know about genetics today.
Darwinism: Darwin's ideas connect well with what we know now about genetics. Differences in species come from random mutations, and natural selection works on these genetic differences.
Lamarckism: While Lamarck was thinking ahead about change and adaptation, he didn’t know about DNA and genetics like we do now. His ideas don’t hold up when tested against current science.
Darwinism: This theory is widely accepted and has a lot of evidence backing it up, like fossils and genetic research. It forms the basis of how we understand biology today.
Lamarckism: While important in history, Lamarckism is mostly seen as outdated and incorrect now. Still, it’s interesting to look at how early ideas about evolution started.
In summary, both theories help us understand evolution, but Darwinism has become the main one in science today. This is mainly because it relies on natural selection and genetics.
