Question

3. In what possible scenario would the female birds evolve to having the singing trait? (5 points)

Answer 1

The possible scenario for singing traits in female birds will be about 26% in Generation 4 species

Explanation:

Singing trait have been common among both male and female birds and it is an ancestral traits. However, singing has been more sex-specific with male birds. Reasons for which birds generally sing are:

• To attract the mates
• While making nests and laying eggs
• For the young birds to recognize their parents

However, various studies prove that the singing trait in female birds is reducing with increase in non-singing female birds over the years due to evolutionary course.

Answer 2

Answer:

I think the birds stopped singing because there are too many predators that found and ate them. If the predators left, or if there were less, more birds will start singing because there will be a less chance of getting eaten or preyed on.
