Question

question 1
which of the following describes an example of convergent evolution?
sharks are fish and dolphins are mammals but they have similar traits because they live in the same environment.
the beaks of the finches on the galapagos islands adapted to the food source available on the specific island where they lived.
the neck length of giraffes adapted to allow the individuals to reach the leaves high on the tree.
during an ice age, the rabbit population shifted from a greater number of individuals with brown fur to an increase in individuals with white fur.

Explanation:

Convergent evolution is when different species evolve similar traits due to similar environmental pressures. Sharks (fish) and dolphins (mammals) having similar traits (e.g., streamlined bodies for swimming) because of living in the same aquatic environment is an example. The Galapagos finch beak adaptation is adaptive radiation (divergent evolution from a common ancestor). Giraffe neck length is adaptation within a species. Rabbit fur color change is natural selection within a population.

Answer:

Sharks are fish and dolphins are mammals but they have similar traits because they live in the same environment.
