Understanding phylogeny is important because it helps scientists understand how living things are related and how they evolved over time. This can be useful in everyday life because it helps humans make better choices in science, medicine, and the environment. For botanists, phylogeny is especially helpful because it guides them in finding new plants that may have useful benefits for people, like medicine or food.

Insects, birds, and bats can all fly using wings, but their wings are not made the same way. Insect wings come from the insect’s outer body, while bird and bat wings are modified front limbs with bones. Even though the wings do the same job, they developed differently and do not share the same origin.

They were mostly small the soft seeds during the El Niño, the birds with smaller beaks were able to eat more easily and reproduce more than the large beaked birds. After the El Niño, the Grants measured the birds again and found that the average beak size in the population was smaller because more small beaked birds survived and had offspring.

This is saying that living things make more offsprings that the environment can support. Since food and water and many more stuff are limited, they have to compete to get what they need.
