Evidence of Evolution

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring. It is a key mechanism of evolution.

Front

What are 'SuperBugs'?

Back

SuperBugs are bacteria that have developed resistance to antibiotics, making them difficult to treat.

Front

Who proposed the theory of natural selection?

Back

Charles Darwin proposed the theory of natural selection after his observations during his visit to the Galapagos Islands.

Front

What is genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population.

Front

What is non-random mating?

Back

Non-random mating occurs when individuals in a population choose mates based on specific traits, rather than randomly.

Front

Why do peppered moths change color?

Back

Peppered moths change color to blend in with their environment, which helps them avoid predation.

Front

What is gene flow?

Back

Gene flow is the transfer of genetic material between populations, which can increase genetic diversity.

Front

What is the significance of the Galapagos Islands in evolutionary biology?

Back

The Galapagos Islands are significant because they were studied by Charles Darwin, leading to insights about natural selection and evolution.

Front

How does camouflage benefit animals?

Back

Camouflage helps animals avoid detection by predators, increasing their chances of survival.

Front

What is the relationship between hippos and whales?

Back

Hippos and whales share a common ancestor, and their DNA is closely related, indicating evolutionary links.
