[U2-L2] Two birds that look very similar to each other have always been considered two distinct species based on differences in
their body size and in where they live. A group of ornithologists studying the two species begins to think they might not be separate species based on observed behavior. What would be the best next step regarding this new hypothesis?
In my opinion, the next step considering the mentioned hypothesis in the question is to perform DNA examinations on the two species in order to observe how genetically identical they are.
Prior to making any kind of conclusions, like publishing the ideas in a scientific journal, there is a need to ensure that the hypothesis is correct. Thus, comparing the DNAs of the two birds in order to access their similarities and differences would be an ideal way to test the hypothesis.
For the given situation above, the best next step regarding the new hypothesis is to r<span>un DNA tests on the two species to see how genetically similar they are. I hope this answer helps. Looking forward to help you again. Have a great day!</span>
The answer is tropical areas. The tropical areas obtain more
radiant energy from the Sun than they lose to space through terrestrial
radiation, and vice versa for polar areas. Earth has an energy remaining in the
tropics and an energy scarcity for the polar areas.
