Millions of years ago, a small population of birds lived on the Hawaiian Islands. Over time, this population evolved into more than 54 separate species, each with different colors, beak shapes, and food sources. Which of the following best explains why the original population of birds evolved into so many different species? A Many of the birds were killed each time a volcano erupted on the Hawaiian Islands.

B The Hawaiian Islands had few predator species to decrease the lifespan of the birds.

C The bird population moved into and adapted to many different environments on the Hawaiian Islands.

D The climate of the Hawaiian Islands rarely changed, which helped the bird population to increase in size.

C. The bird population moved into and adapted to many different environments on the Hawaiian Islands.

Why:

When a species adapts itself to new environments certain features will change, such as beak size, wing use, and even height, these are all changed depending on what the species does and needs to survive. These birds all changed food sources which made them have to adapt their beaks over time to new sources, and natural color to over generations camouflage themselves better from predators.

(Hope this was a good explanation.)

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.
