Question

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. Each spring when the worms
reproduce, they have about 500 babies but only 100 of these 500 ever become old enough to reproduce.
Identify a type of variation in the worms.

Answer 1

1 diurnal worms and nocturnal worms
2Nocturnal
3 There will only be nocturnal worms
4 There will be some nocturnal birds.

Answer 2

Darwin's Natural Selection Worksheet Read the following situations and fill in the chart for each of the four parts of Darwin's theory of

natural selection.

D There is a species of worms that eat at night (nocturnal) and ones 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. Each spring when

the worms reproduce, they have about 500 babies but only 100 of these 500 ever

become old enough to reproduce.
