Evolution, Ecology & Sustainability

The dog breeds we have today were developed through:

1. natural selection
2. artificial selection (selective breeding)
3. sexual selection
4. acquired selection

The best description of natural selection is

1. The survival of the fittest
2. The struggle for existence
3. The reproductive succes of the members of a population best adapted to the environment
4. the overproduction of offspring in environments with limited natural resources

Darwin proposed the idea of 'survival of the fittest'. Which of the following individuals are meant by 'fittest'?

1. The individuals who live longest
2. The individuals who are the strongest
3. The individuals who get the most offspring
4. The individuals who are the biggest

What is required for natural selection to occur?

1. Variation within a species
2. Variation between species
3. No change in environmental factors

What might happen to a species if it didn't have a a lot of genetic variation to adapt to a
changing environment?

1. It might evolve into another species
2. It might change its genotype to get more variation
3. It might become a less complex species
4. It might become extinct
