Homologous structures
Analogous structures
Vestigial structures
Fossil structures

When looking at two tree frogs, a student noticed that one of the frogs had longer toes than the other. This is an example of
On Darwin's 5 year journey sailing around the world, he was amazed by the ___________________ of living things that he saw.
diversity
genes
offspring
evolution
Consider what caused the variation in finch beaks on the Galapagos Islands. How did it bring about new species of birds?
The finches all decided to change their beaks by themselves.
The finches lost their beaks as they flew to different islands and regrew them.
The finches adapted to the environment allowing them to survive in their new surroundings.
All the choices.
How do environmental factors contribute to evolution by natural selection?
Environmental factors are ALWAYS negative and hurt animals.
A change in the environment is always postive.
Environmental factors do not affect populations to evolve.
A change in the environment can affect an organism's ability to survive and may lead to 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?
The moths were not affected by the change to the trees.
The number of black spots on the moths increased.
The number of white spots on the moths increased.
The moths migrated to areas with less pollution.
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?
The two butterfly species have adapted to look like each other so that they could breed.
Over time the non- poisonous butterfly has adapted to look like the poisonous butterfly to help protect it from predators.
Over time the two butterfly species have adapted to look like each other because they eat the same food.
The poisonous butterfly has adapted to look like the non- poisonous butterfly so that it can live in the same environment.
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
vestigial structures
analogous structures
homologous structures
adaptation
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.
convergent evolution
divergent evolution
coevolution
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.
convergent evolution
divergent evolution
coevolution
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.
convergent evolution
divergent evolution
coevolution
