1) Which of the following provides structural evidence for evolution? a. A fossil shows an extinct animal similar to a modern animal. b. A comparison of similar bones in the legs of a human, a dog, and a bat. c. A genetic analysis of twon animals shows similar sequences of DNA. d. The embryos of two animals shows similar sequences of DNA. 2) Charles Darwin studied the finches of the Galápagos Islands and found that their beaks vary in shape and size. Darwin found that the finches that ate mostly insects had long, narrow beaks. Finches that ate mostly seeds had shorter broad beaks to crush seeds. Which statement below describes how natural selection resulted in the four types of finches shown above? a. The residents of Galápagos Islands selectively bred together finches having the traits they wanted them to have. b. The narrow-beaked finches came first and evolved into the broad-beaked finches through a series of natural mutations. c. The broad-beaked finches wore down their beaks digging for insects and passed these narrow beaks on to their offspring. d. Over time, the finches that were born with beaks better suited to the available food suply in their habitats survived and reproduced. 3) The teacher makes an argument to the class for why fire could be considered a living thing and then asks what is wrong with that argument. Tatiana raises her hand and replies with one characteristic of life that fire does not have, Which of these could have been Tatiana´s answer? a. Fire does not grow and develop.

1) Which of the following provides structural evidence for evolution?

a. A fossil shows an extinct animal similar to a modern animal.

b. A comparison of similar bones in the legs of a human, a dog, and a bat.

c. A genetic analysis of twon animals shows similar sequences of DNA.

d. The embryos of two animals shows similar sequences of DNA.

2) Charles Darwin studied the finches of the Galápagos Islands and found that their beaks vary in shape and size.

Darwin found that the finches that ate mostly insects had long, narrow beaks. Finches that ate mostly seeds had shorter broad beaks to crush seeds. Which statement below describes how natural selection resulted in the four types of finches shown above?

a. The residents of Galápagos Islands selectively bred together finches having the traits they wanted them to have.

b. The narrow-beaked finches came first and evolved into the broad-beaked finches through a series of natural mutations.

c. The broad-beaked finches wore down their beaks digging for insects and passed these narrow beaks on to their offspring.

d. Over time, the finches that were born with beaks better suited to the available food suply in their habitats survived and reproduced.

3) The teacher makes an argument to the class for why fire could be considered a living thing and then asks what is wrong with that argument. Tatiana raises her hand and replies with one characteristic of life that fire does not have, Which of these could have been Tatiana´s answer?

a. Fire does not grow and develop.

b. Fire cannot reproduce.

c. Fire does not have genetic material.

d. Fire does not use energy.

genetically ________________________________ to the parent.

c. ___________________________ is the difference in inherited traits an organism has from others of the same species.

d. _____________________________ is the process by which populations change over time.

5) Use the figure to answer the following questions:

6) True or false?

8) If you were a scientist examining the DNA sequence of two unknown organisms that you hypothesize share a common ancestor, what evidence would you expect to find?

9) Explain why the pattern of differences that exists from earlier to later fossils in the fossil record supports the idea that evolution has taken place on Earth.

10) What is the significance of the similar number and arregement of bones in a human arm and a bat wing?

11) Use the table to answer the following questions:

a. What do the data suggest about how related turtles are to humans compared to tuna and chimpanzees?

b. If there are no differences between the amino acid sequences in the cutrochrome c protein of humans and chimpanzees, why aren´t we the same species?

12) Which word means “the remains of imprints of once-living organisms found in layers of rock”?

13) Could life as we know it exist on Earth if air contained only oxygen?

14) How is a fish similar to a tree?
