I’ve annotated your question and colour coded the answer, (the dotted line represents current bird population) and blue line represents what the population will look love after natural selection
An air mass is a large volume of air in the atmosphere that is mostly uniform in temperature and moisture. Air masses can extend thousands of kilometers across the surface of the Earth, and can reach from ground level to the stratosphere—16 kilometers (10 miles) into the atmosphere.
Air masses form over large surfaces with uniform temperatures and humidity, called source regions. Low wind speeds let air remain stationary long enough to take on the features of the source region, such as heat or cold. When winds move air masses, they carry their weather conditions from the source region to a new region. When the air mass reaches a new region, it might clash with another air mass that has a different temperature and humidity. This can create a severe storm.
I believe it's Sympatric Speciation.

Answer:
The correct answer would be - Cells begin dividing faster, leading to cancer.
Explanation:
In the process of the cell cycle, there are several checkpoints that ensures that the cell is all set to move to next phase, the cell that not match the requirements cell have not move to next phase.
These checkpoints control the rate of cell proliferation or division and if a dividing cell fails to pass through any checkpoints due to the mutation, it is most likely divide uncontrollably and lead to cancerous or tumor cell.
Thus, the correct answer is - Cells begin dividing faster, leading to cancer.
