There are 2 types of worms: worms that eat at night (nocturnal) and worms that eat during the day (diurnal). The birds eat during the day and seem to be eating ONLY the diurnal worms. The nocturnal worms are in their burrows during this time.

1. Identify a type of variation in the worms.

2. Which variation is most favorable?

3. In 50 years, what will natural selection have most likely done for the worms? (Hint: What type of worm will be the most common. )

4. What adaptations might occur in the birds in 100 years?

Answers

We can confirm that one variation in the worms is the adaptation to become nocturnal eaters instead of the more dangerous diurnal eaters.

Why are nocturnal worms favored?

Nocturnal worms are favored over diurnal eating worms given that the main predator of worms, birds, hunt during the day. This puts the diurnal worms are a much higher risk of being consumed. Through natural selection, this will likely result in most worms being entirely nocturnal within the next 50 or so years, which can in turn lead to the evolution of more nocturnal hunting bird species.

Therefore, we can confirm that one variation in the worms is the adaptation to become nocturnal eaters instead of the more dangerous diurnal eaters, which will likely be the most common variation over time, due to natural selection.

Fossil fuels are matter that is made up of decaying organic matter, such as animals and plants. Fossil fuels are made for millions of years. They are used in running big machines and generating power plants.

Fossil fuels are burned in running machines or run a car, and the gases that came from this burning cause the earth to warm.
