Answer:
Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.
To give one classic example, the forelimbs of whales, humans, and birds look quite different on the outside. That's because they're adapted to function in different environments. However, if you look at the bone structure of the forelimbs, you'll find that the organization of the bones is remarkably similar across species. It's unlikely that such similar structures would have evolved independently in each species, and more likely that the basic layout of bones was already present in a common ancestor of whales, humans, and birds.
A would be the best answer if you read on it they talk about how much damage it really did
Answer:
Through adaption, Darwin observed that finches beaks changed over time.
Explanation:
The intermediate gastric glands produce most of the digestive substances secreted by the stomach. These glands are narrow tubules composed of three major cell types: zymogenic, parietal, and mucous neck cells.
The trachea is a single tube through with oxygen passes to the double-tubed bronchi as we breathe air inside. The two tubes of bronchi are called left and right bronchi and are often termed as alveoli and bronchioles
I believe the answer is B!
