How did the color of the foxes’ environment change? Explain what happened to the foxes over many generations.
xxMikexx [17]

Answer:

The answer is below

Explanation:

1. With the aid of natural hues, the fox can change its color based on the environment it found itself in. For example, during summer and spring, fox color changes to dark to provide itself cover in the environment that is characterized by the brown dirt. Similarly, the fox color changes to white during winter and fall to blend with the snow.

2. In a bid to domesticate fox, it has been observed over many generations that the domesticated fox compared to wild fox has floppy ears and curly tails. The stress hormone level has reduced significantly and they possess a smaller adrenal gland.
