Charles Darwin was from this old world European country.
What is England?

This graph below represents this pattern of selection. 
What is disruptive selection?
100
An adaptation is created when a random ___________ ends up helping an organism survive and reproduce in their environment.
What is a mutation?
100
These structures have lost most, or all, of their function.
What are vestigial structures?
100
Identify the type of reproductive isolation:
Two species of snails have shells that coil in opposite directions, so their reproductive organs don’t align properly for mating.
What is structural isolation?
200
Darwin's theory was partially inspired by these two organisms that he observed in the Galapagos Islands.
What are the tortoises and the finches?
200
This graph below represents this pattern of selection.
What is directional selection?
200
An observable, physical adaptation, like the spines on a cactus, is also called this.
What is a structural adaptation?
200
Structures which are similar in function but very different in structure, like those show below, are called this. 
What are analogous structures?
200
Identify the type of reproductive isolation:
Two species of fireflies flash their lights in different patterns to attract mates. Each species only responds to its own flashing pattern.
What is behavioral isolation?
300
Slang for natural selection, it's not the struggle for the most muscular
What is "survival of the fittest"?
300
What pattern of selection is illustrated below:
A population of pale moths blends in to the bark of a birch tree. However, as factories are built and soot accumulates on the trees, the trees get darker, meaning the lighter colored moths are easier for predators to see and eat. Overtime, the moth population tends to get darker and darker.
What is directional selection?
300
An action that an organism takes that improves it's ability to survive and reproduce is called this.
What is a behavioral adaptation?
300
The branch of biology which studies the development of unborn/unhatched organisms.
What is embryology?
300
Identify the type of reproductive isolation:
A river forms and splits a population of rodents into two groups. Over time, the groups evolve separately and no longer interbreed.
What is geographical isolation?
400
The long process of change which occurs over many years, and the trademark of Darwin's theory.
What is evolution?
400
What pattern of selection is illustrated below:
On some island, there are very small seeds and very large seeds. Birds with small beaks are capable of picking up and eating the small seeds, and birds with large beaks are able to crack open and eat the large seeds. However, birds with medium beaks struggle to eat either seed.
What is disruptive selection?
400
Internal or cellular changes that help an organism survive and reproduce in their environment is called this.
What is a physiological adaptation?
400
Homologous structures have similar __________ but different ____________.
what is similar structure but different function?
400
Identify the type of reproductive isolation:
Two species of moth live in the same forest but one is active and mates in early spring, while the other doesn’t begin mating until mid-summer.
What is temporal isolation?
500
This metric measures how good an organism is at having babies, and not how strong it is.
What is reproductive fitness?
500
What pattern of selection is illustrated below:
In humans, medium sized babies usually have the highest rates of survival. This is because small infants tend to be underdeveloped and struggle once they are born, while very large infants tend to be difficult to birth and are prone to injury.
What is stabilizing selection?
500
Birds have naturally hollow bones, which help to reduce weight and make flight easier to achieve. This is an example of what kind of adaptation?
What is a structural adaptation?
500
These structures can be used as evidence of a recent common ancestor between species.
What is a homologous structure?
500
Different species of birds are incapable of breeding with each other and producing viable offspring. Why are they considered different species?
What is reproductive isolation?
