A) Imagine a major volcanic eruption has dramatically changed the environment on an island
such that the average temperature and available sunlight are much lower. Of the following
species present on that island, which species is most likely to adapt and evolve to this change
instead of going extinct? (1 point)
a bird species with specific nesting requirements that only feeds on one type of seed.
a large mammal species with a low reproduction rate and specific food needs.
an insect species with a high reproduction rates and a significant mutation rate
a reptile species with a high reproduction rate and very similar individuals.
An insect species with high reproduction rates and a significant mutation rate.
