These are thought to have brought water to earth's surface
What are comets or meteorites
100
The likelihood an organism is to survive and reproduce in their environment
What is biological fitness
100
Sexual selection leads to differences in phenotype between males and females. This phenomenon is known as:
What is sexual dimorphism
100
Mutations, sexual reproduction, gene flow, and genetic drift all increase
What is genetic variation
100
This trait makes a species a hominin
What is walking upright
200
These were the 1st organisms responsible for changing the atmosphere of Earth because they use photosynthesis to make glucose and oxygen.
What are cyanobacteria
200
In the image this litter of kittens all have different phenotypes. Which of the FOUR factors does this image show?
What is variation due to mutation and sexual reproduction
200
The image below shows the skulls of different species of waterfowl... This type of adaptation is shown by the differences in the beaks and the skulls of these birds?
What is anatomical adaptations
200
The type of speciation in which there are barriers to successful interbreeding between individuals of different species in the same community is referred to as
What is Sympatric Speciation
200
All human like species (hominins) have their origins in this continent.
What is Africa
300
3 types of evidence Darwin had access to and used as evidence for "Descent With Modification"
What are fossils, comparative anatomy and biogeography
300
Human birthweight favors individuals that express the intermediate phenotype. This is an excellent example of...
What is stabilizing selection
300
Favors one or the other of a phenotypic extreme
What is directional selection
300
Speciation created by a physical separation of organisms.
What is allopatric speciation
300
This is the defining characteristic of the genus Homo?
What is brain growth
400
These are the islands off of the coast of South America that Darwin did the majority of his work
What are the Galapagos Islands
400
Look at this image. This is an example of...
What is Intrasexual selection
400
Select which of the FOUR factors this image best represents
What is competition for limited resources
400
Two organisms breed but fail to create fertile offspring. An example would be when a male horse and female donkey create a Hinny.
What are post zygotic isolation
400
The timing of evolution in which long periods of evolutionary change are interrupted by bursts of rapid evolutionary change is called
What is punctuated equillibrium
500
Similarities between amino acid sequences found in different species would be an example of this type of evidence for evolution
What is molecular evidence or protein comparisons
500
Evolution occurring on its smallest scale. A change in allele frequency over generations
What is microevolution
500
A version of a trait
What is an allele
500
New species arise in the same geographic region.
What is sympatric speciation
500
The result of extinction level events. The sum of small evolutionary changes over large amounts of time including speciation.
What is macroevolution
600
This technology for dating rocks of the Earth was developed in the early 1900s and uses radioactive isotopes to determine the exact age of rocks.
What is radiometric age dating (absolute age dating)
600
The mechanism for evolution seen here:
Founders Effect (Genetic Drift)
600
The type of adaptation seen in the image below:
Heart rate and oxygen consumption during hibernation
What is physiological
600
In the fossil record, horse fossils show steady change over a long period of time. This is representative of this pattern for evolution:
What is gradualism
600
3 post-cranial characteristics that indicate bipedalism
Sciatic notch, knock-knees, S curve of spine, Flared hip bones
