When a female bird chooses a mate because of his brightly colored feathers, this is an example of

Answer 1

sexual selection?

Answer 2

When males provide no obvious resources, such as food or protection, females may choose to mate with the males that appear to have the best genes. How do they know which males have good genes? by knowing color .And why don't males just cheat by faking the traits associated with such genes? In 1975 Amotz Zahavi of the University of Tel Aviv in Israel suggested that females assess only those traits that are honest indicators of male fitness--a hypothesis known as the handicap principle. Honest indicators, which are "costly" to produce and maintain, should be associated with the most vigorous males.

Answer 3

Wow, nice answer.

Answer 4

Having said that, I do think it's more complicated. :)

Answer 5

:) i am still wondering how come it is a question of mathematics ..and what if we take an attempt to solve this sexual selection mathematically :)

Answer 6

No, I think the site is a bit weird.
Did you ever answer a biology Q? If so, then you see biology Q even when you think you are in mathematics.

Answer 7

exactly !!

Answer 8

It's more than a little spooky.

Answer 9
