Which of these best describes natural selection?
In a lighter environment, such as lighter tree trunks, will darker or lighter moths have a better chance at survival?
In a lighter environment, how will natural selection change the colour of the population over many generations of parents and children?
If the environment became polluted and darker, predators that eat moths would be involved in natural selection. Which moths would they probably eat more of in the darker environment?
The environment became darker with lava rocks. Natural selection changed the colour of the mice over many generations. How did their fur colour change over time?
Why did the lava-mice fur colour match the colour of the lava rocks after many generations?
Sometimes a sandy coloured mouse is born onto the darker lava rocks. What will probably happen to it?
What could be another way to describe natural selection?
Some rabbits are born that can run very fast. Some are quite slow. Rabbits are eaten by foxes. How will natural selection work?
If foxes catch and eat the slower rabbits, what will the next generation of rabbits be like, compared to the one before?
