Classify each example or description into the correct evolutionary mechanism.
svetlana [45]

Among evolutionary mechanisms, there can be mentioned non-random matings (1 and 8) , mutations (3 and 6), genetic drift (2, 4 and 5), and genetic flow (7).

<h3>What are evolutionary mechanisms?</h3>

These are different mechanisms that change allelic frequencies and genotypic frequencies conserning the expected ones if populations were under Hardy-Weinber equilibrium.

When these mechanisms are going on, populations evolve.

Among them, we can mention,

  • Non-random matings  
  • Mutation
  • Genetic drift
  • Genetic flow

In the attached files you will find a better explanation about evolutionary mechanisms

Examples classification,

1)  non-random matings

2)  Genetic drift - founder effect

3)  Mutation

4) Genetic drift - founder effect

5)  Genetic drift - bottleneck effect

6)  mutation

7)  Genetic flow

8)  Non-random mating

timofeeve [1]

The correct answer is: B) As land plants became more complex, animal life did as well.

This is because land could not be colonized by other organisms such as animals until land plants became established-there was nothing for animals to feed on.
