Answer:Fossils provide evidence for the evolutionary change through now extinct forms that led to modern species. For example, there is a rich fossil record that shows the evolutionary transitions from horse ancestors to modern horses that document intermediate forms and a gradual adaptation o changing ecosystems
Explanation:
Answer:true
Explanation:since they are on different islands it’s hard for them to get to different islands
Body maintain Homeostasis by Negative Feedback mechanism. Because the stimuli causing the disturbance in the Homeostasis of the body is to be counteracted by a mechanism.

What is homeostasis?</h3>
The Homeostasis of the body is defined as the regulation of the internal environment of the body when there is a change.
In Positive feedback mechanism, it increases the response of the stimuli In temperature regulation, the stimuli are hot and cold.
Both are controlled by a opposing negative feedback mechansim that is when the body temeprature increases it is decreased to normal by a negative feedback mechanism , likely when the body temeprature is decreased(cold) , the body will increase the Body temeprature to normal By a Negative feedback mechanism that is exactly opposite(opposing) to the Former Negative feedback mechanism pathway.
In termparature regulation when body temperature raises ----->detected by nerve endings in the skin--Hypothalamus -----> signal to blood vessel for dilation activation of the sweat gland-the tempertaure is maintained to normal. -> signal send to the>heat is lossed and when body temperature decreases -----> detected by nerve endings in the skin------> signal send to the hypothalamus -----> signal to blood vessel for constriction inhibition of secretion from sweat gland, shivering ---->heat is generated -->normal.

Answer:
3. Size could
4. Beak's are advantageous because they have to be fit to eat the seeds that they need
Explanation:
size can affect because the bigger birds can fight the smaller birds off when they are eating the same product. Even with same beaks bigger birds will have an advantage.
