Natural selection is a fundamental process in evolution, driving adaptation through the interplay of random mutations and environmental pressures. This article delves into the mechanics of natural selection, common misconceptions, and its role in shaping the diversity of life on Earth.
Unlike cloned potatoes wiped out by disease, viruses thrive due to rapid mutation. Explore why genetic variation is key to species survival and how it shapes our differences.
DNA mutations are changes in the genetic code that generate variations among individuals. These mutations are crucial for evolution, influencing traits and adaptations. While most mutations are neutral or harmful, some can enhance an organism's fitness, driving evolutionary progress.
Forget bears turning into lions! Evolution is about tiny changes adding up over millions of years. Explore how apes gradually evolved into humans & why a chimp's baby is still a chimp. Learn the secrets of our incredible diversity!
Explore how natural selection shapes our traits and understand why not all characteristics are evolutionary adaptations. Learn about adaptive and non-adaptive traits through engaging examples.
"Survival of the fittest" isn't Darwin's original term! Discover the economist who inspired him & how Darwin used it to explain evolution.
High survival rates don't stop evolution! Discover how mutations & genetic drift ensure humans keep evolving despite modern medicine.
Humans come in all shapes and sizes, but our DNA is surprisingly similar. Learn why our limited genetic diversity might be a surprise and how it affects our species' survival.
Evolution isn't about improvement but adaptation. Discover why humans, sharks, and bacteria are equally evolved and what the future might hold for our species.
Divergent evolution explains how related species develop distinct traits over time. This fascinating process, driven by adaptation to different environments, is behind the incredible diversity of life on Earth. Let's delve deeper into what it is and how it works!
Discover how scientists study evolution, from unexpected experiments with Italian wall lizards to forensic-style investigations of Earth's past. Learn about observable changes in species, the challenges of studying human evolution, and how researchers use various tools to unravel life's complex history.
