Given what we know, we can confirm that if a population of animals has a short gestational period and travel in large groups, this will result in increased mating leading to higher birth rates and an increase in individuals.
<h3>How is the gestational period related to birth rates?</h3>
- The gestational period refers to the time it takes an organism to fully develop a newborn.
- This means that a pregnant female of this animal group will not take very long to give birth.
- This also implies a short recovery period.
- This results in the females being able to breed more often and thus will increase birth rates.
Therefore, given that the females in the group will carry the fetus for very short amounts of time due to the short gestational periods, they will become available to breed more often and thus will result in higher birth rates and increased population size.
