Andrews [41]

The beauty of plants being the reason for faster blooming cannot be tested using the scientific method.

<h3>The scientific method</h3>

It is a rational order of steps through which scientific investigations are conducted.

Beauty is a relative term and can be generally subjective. What is beautiful to one person might not be beautiful to others.

<u>Hence, the first thing to establish that two organisms are not of the same species is the inability to breed with each other. If an eventuality occurs and they are able to breed, the resulting progeny would be invalid</u>.

Therefore the fact that the golden-cheeked warbler and the black-throated green warbler do not breed with each other where their territories overlap is enough information to determine that the birds are separate species.
