Answer:

If bird song promotes an individual's ability to attract a mate and reproduce, then the song has an <u>     function</u>

<u />

Explanation:

Within a community, certain novel traits are fixed because they impart beneficial adaptations on an individual in their ecosystem (like mate attraction). Such modifications enable such individuals to live longer than their peers, and breed over time to produce more offspring who also exhibit these traits.

Natural selection takes place and is determined by the fitness of an individual , it contributes to evolutionary change as individuals with certain traits reproduce, the traits become fixed and prevalent within the population.

What did darwin believe was the primary cause of evolution?
lesya692 [45]

→ Darwin believed that the need to adapt, in similar words, the changes occruing in the environment caused evolution.

The main cause of evolution, according to Darwin, was natural selection. Natural selection is a process in which a group of organisms with certain characteristics survive and thrive, in comparison to other organisms with different characteristics. This idea basically means that having some characteristics makes you suited for an environment.


And how would that ↑ explain Evolution?

Well, evolution is the change in species that occurs during time. But for you to change, there must be a cause for that change, which is none other than the need to survive, reproduce, etc.


→ As mentioned before, not all characteristics are enough to surive, and hopefully the image pasted below will help you.



Hope it helped,
