Which of the pictures above would be examples of homologous structures? (pick 2)

On Darwin's 5 year journey sailing around the world, he was amazed by the ___________________ of living things that he saw.

Consider what caused the variation in finch beaks on the Galapagos Islands. How did it bring about new species of birds?

How do environmental factors contribute to evolution by natural selection?

The peppered moth was originally light colored with some dark spots. It was well camouflaged from birds and bats on light colored trees. Over time, the light colored trees were covered in a layer of black soot due to industrial pollution. What happened to the peppered moth population?

Two species of butterfly look almost identical, even though they are not related. One of the species is poisonous to birds, causing them to become ill, while the other species is not poisonous. What is the MOST LIKELY reason that the two species of butterfly look so similar?

Suppose orange beetles and green beetles live in the same environment. Green beetles are harder to see on leaves, so birds eat primarily orange beetles. According to the theory of natural selection, in the future orange beetles will

Long ago, humans domesticated grey wolves. They began to breed wolves that had certain traits that they preferred (fur color, size, temperament, etc.) Over time, this led to changes in the grey wolves. This would be an example of

(a)  

A structure that no longer serves a function necessary for survival; an evolutionist would argue that it is left over from our evolutionary past - that the common ancestor of the species needed that structure for survival

Ostriches (birds) and giraffes (mammals) are both native to the savannahs of Africa.  They eat food that is high off the ground and share the same characteristic of an elongated neck.

The kit fox lives in the desert and has large ears with greater surface area that keep the fox from getting overheated.  The red fox lives in the forest and has a red coat that keeps it camouflaged.

A form of evolution where two separate populations of the same species accumulates enough differences over time to become two distinct species, becoming more and more dissimilar.

Which species evolved first? (Which species is the oldest?)

Which species is not carnivorous?

Which species is most closely related to prosimians?

Which trait is letter F?

The picture is an example of a ______.

From our Lab: Artificial Selection Simulation, what are the potential benefits and drawbacks of artificial selection? Consider the impact on biodiversity, the environment, and human society.

From the Lab: Human Adaptations, what conclusions can you draw about the importance of thumbs in daily human activities? How might the loss of thumb functionality impact a person's ability to perform everyday tasks?

From our Lab: Habitat Fragmentation and Species Survival, what are some real-world examples of habitat fragmentation caused by human activities? How do these examples relate to the simulation in this lab activity?

From our Lab: Darwin's Finches, what were some hidden factors (did you develop a strategy) you realized while doing these trials to help your “beak” get more “seeds” during the trial?
