Why is it important to study evolution and from where organisms have originated

1. it is important to study evolution in order to solve biological problems that impact our lives.

2. it is also important to study evolution in order to  stay one step ahead of pathogenic diseases and able to find solutions to it

Researchers must understand the evolutionary patterns of disease-causing organisms.

It is noted that all life on Earth evolved from a single-celled organism that lived roughly 3.5 billion years ago.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
