Charles Darwin's Natural Selection has transformed life as we know it. What surprised you or impacted you the most about Darwin or Evolution? Share with us below!
Natural selection works over colossal periods of Time! Smaller, incremental variations add up over generations to produce fresh species and awe-inspiring biodiversity. Think about the countless adaptations that have occurred over millions of years!
Let's set some evolution myths straight! Myth: Man came from monkeys. Fact: Man and monkey came from the same ancestor. Myth: Natural selection is a willful decision. Fact: It is a blind process based on environmental pressures. What are some other myths you've heard?
Evolution is not old news! We see natural selection in action everywhere we look: germs developing antibiotic resistance, bugs developing pesticide resistance, and even changes in animal populations due to global warming. What makes you think of adjusting to our world?
Darwin's finches are the ultimate display of the evolution spectacle! On the Galapagos Islands, different types of finches evolved differing beak types, perfectly adapted to each of their specific food supplies. A living laboratory for natural selection!
The magic of natural selection is when useful traits get passed on! Children born with useful traits are more likely to survive and reproduce, passing on those traits to their young. It's how populations change over time!
Natural selection starts with Variation! From fur color to beak shape, individuals within a species are small variations. This image shows different fishs in the same species.
"Survival of the fittest" is abused! It's not about being strongest, but best adapted to a particular habitat. A chameleon's camouflage is "fit" in the jungle, but not on a snow-covered mountain.
In any environment, there is competition for life. Organisms compete for food, water, and reproduction. Organisms that possess useful traits stand a better chance of being the survivor in this battle of life. What do you think is the biggest challenge to survival in the wild?
Wondered how life got so diverse? Meet Charles Darwin! ? His travels on the HMS Beagle resulted in a revolutionary idea: Natural Selection. It's not just "survival of the fittest," but rather about traits that allow organisms to survive & reproduce in their environment.
