From the Egg viability hypothesis, we can predict the following;
A. Probability of hatching failure will
be higher for eggs laid later within a clutch.
This is because viability of unincubated eggs decline overtime.
B. The probability of hatching fail will be higher for eggs laid later within a clutch.
This is because large clutch affects or changes nest micro-climate which result to increase in water loss during incubation period.
<u>Answer:</u>
<em>It is not true to say that common ancestors occurs only within a single species rather two species with similar traits might have a common ancestor. </em>

Phylogenetic tree are drawn and studies are done to understand the ancestor of a species. The evolution has occurred from the ancestor to the new species formed.
Lack of natural predators allows for unrestricted growth
The answer is a. the troposphere
