The above scenario is an example of an exponential growth.
<h3>What is an exponential growth?</h3>
An exponential growth can be defined as a situation in which the population size of a species of living organism grows faster and quickly as the population gets larger.
This ultimately implies that, an exponential growth generally result in a a population explosion over time.
In this scenario, we were told that the population of European starlings increased to hundreds of millions. Thus, this is an example of an exponential growth.
Humans are classified as mammals because humans have the same distinctive features (listed above) found in all members of this large group. Humans are also classified within: the subgroup of mammals called primates; and the subgroup of primates called apes and in particular the 'Great Apes'
