What is the process in which populations CHANGE gradually over time?

What do you call similar structures that related species have inherited from a common ancestor?

What do we call structures that no longer perform their original function?

What do you call a characteristic that allows an organism to survive in an environment?

Hibernation is an example of which type of adaptation?

Beak shape, camouflage, and webbed feet are all examples of which type of adaptation?

Select ALL that show evidence of evolution.

Parrots are tropical birds. However, in some areas of New York City, some parrots have been able to survive outdoors year-round. These parrots survive, while most others cannot, due to

In the past, humans developed varieties of dogs, such as the German shepherd and the bearded collie, using

The overall changes in the population of mice can be explained best by

Starting in 1954, commercial fishers in the northwest Pacific were paid by weight, rather than by the individual fish, for pink salmon. The fishers increased the use of a type of net that selectively catches larger fish. Which of the following effects did this change in fishing technique most likely have on the salmon population over the next 20 years?

A change in a species over time is known as:

A type of evolution on a small scale that affects a species or a population, such as developing antibiotic resistance

A type of large scale evolution where one species can serve as an ancestor to one or more new species that usually takes a very long period of time

Genetic variation among offspring is caused by:

Which term is best described as organisms that have the adaptations best suited to their environment tend to survive and have more offspring.

Traits in a population that increase survival changes eventually become more prevalent in a population because

Moths with black wings make up nearly 80% of a population, while moths with white wings make up only 20%. 65 years ago, white wings were seen in nearly 75% of the population, and black wings were less common. What might account for this?

Even though they may not make sense to us, traits that increase and organism's_____________, are most favorable in a population.

Two populations of different bird species were studied. It was found that there were 57 genetic differences found in species A and 37 differences in species B. Which species is more likely to survive as the environment changes?

Often times, a mating pair in a species will produce many offspring, even more than the 2 required to replace themselves. This is because not all offspring survive and is known as:

In Darwin's finches, all the birds of the same species do not have the exact same sized beak. This is known as:

Darwin discovered that all of his finches likely had a common ancestor from the main land, but the beaks of each species of the birds he studied on each island varied based on the food available to them there - this is known as

In the 1970's researchers picked up from Dawrin's Galapagos finch studies. Over a 10 year period, one particular island received less rain, and the seeds become larger and harder to crack. Upon measuring the beaks of one species of finch on the island, they discovered that the average beak size in in the population had increased, likely to better crack the larger seeds. This is an example of:

4 species are compared:

Species A reproduces asexually every 10 days, producing 100 offspring at a time.

Species B reproduces sexually every 10 days, producing 100 offspring at a time

Species C reproduces asexually every 22 days, producing 11 offspring at a time.

Species D reproduces sexually every 22 days, producing 11 offspring at a time.

**Which species has a a better chance of surviving environmental change?

This image is an example of:

In a population of rats, a mutation has developed that makes the rats fur white. The soil that the rats frequent for food is black in color and the white rats do not live long due to the presence of Owls. What will happen to the allele for white fur allele?

Imagine that the sprinkles in each container represents an individual of the population in that area. Which population will be less likely to survive a change in the environment?

In a rapid early ice age, many species died out that had persisted for a very long period of stable environmental conditions. After a long ice age, volcanoes emerged from the ice, filling the atmosphere with gasses, which trapped the sun's heat, warming the earth. The fossil record shows thousands of new species emerged during this time, seemingly all at once, calling it the Cambrian Explosion. This is best known as:

Birds and insects both fly, but do not seem to share a recent common ancestor, and their win structures are very different. This is the result of:

The Hardy-Weinburg principle includes each of these except:

When one ancestral species gives rise to multiple species that are different from one another, this is known as:

A large valley opens up after an earthquake, separating a population of snakes. The 2 separated snake populations have different allele frequencies, and over many years, become more and more different from one another. What caused them to change?

In some snake species, there are remnants of leg and arm bones, even though snakes do not have arms and legs. These are known as what kind of structures?

In whale flippers, we see the same bones that humans have in their arms, just in different proportions (length and size) as their mammal ancestors lived on land. This also demonstrates that we share a distant common ancestor with whales. These are known as what kind of structures?

Which organism seems to be most closely related to humans?

Which line of evidence for biological evolution is studied by paleontologists?

This image shows 3 different ways to draw the same phylogenetic tree to represent the evolutionary history of these species. Which 2 species are most different from species E?

Species A has 47 genes in common with Species B and 64 genes in common with Species C. Species D has 21 genes in common with Species B and 82 Species in common with species C. Which of these statements are correct

What is the study of organisms at the early stages of development?

What does the image represent?

Body parts that share a common function, but not structure would be considered

Combined alleles of all individuals in a population is called

Which of the following must occur for speciation to happen?

The lava released by a volcanic eruption separates two populations of a species of monkey. What does this represent?

Gentoo penguins will present a mate with a pebble that they find to attract a mate. Emperor penguins have a specific call and movement that they make to attract a mate. Which type of isolation do these penguins demonstrate?

Which is an example of temporal isolation?

When individuals choose traits possessed by the opposite sex it is called…

Genetic Drift:

In convergent evolution, organisms share physical similarities because they

Cichlid fishes in lakes of the East African Rift. The lakes in this area are believed to support and sustain about 2,000 different species of these fish, each with different ecological and morphological characteristics such as body size. These lakes form a fragmented landscape that bio-geographically isolates the different species of cichlid fish from one another, allowing them, and many of the organisms they live with, to evolve separately.
