Darwin wrote many of the premises of 'The Theory of Evolution by Natural Selection' by noting differences in the _________ of closely related ______________, while studying in the Galapagos Islands. A) feet, finches. B) beaks, finches. C) feather color, tortoises. D) dietary preferences, tortoises.

Answer 1
Answer:

The correct answer is B. beaks, finches

Explanation:

One of the main elements Darwin used to write "The Theory of Evolution by Natural Selection" was his observation of finches on the Galapagos island. Charles Darwin visited Galapagos during the 1830s and in there he observed multiple species of finches that differ in the shape of their beaks. This caught Darwin's attention who determined the shape of the beak varied according to the diet the species had. For Darwin, this shown all the finches derived from the same ancestor and their beaks and other features were the results of natural selection and evolution. Thus, Darwin wrote his theory by noting the differences in the beaks of closely related finches.
Answer 2
Answer: the answer to the question is B because he studied the finches for the fact that they lived on different islands and because of that the birds evolved their beaks to survive in their environment hope this helps

Can you name a species that can only be found in Alaska (and nowhere else in the world)?

Answers

Some species we see in Alaska and nowhere else in the Wolrd are:

Bats
Shrews
Bears
Seals
White Wolfs
Sea lions
Racoons
Walrus. 

Bears, Seals, White Wolfs and Sea lions survive the cold weather much more than those other animals. 
The Spruce Grouse can be an option.

The Spruce Grouse is a bird endemic to the region of Alaska that is unique, since from all the Grouses, this is the one that spends the most time on trees.
