Which species (I, J, or K) is the closest relative to Species H?
Species I
Species J
Species K
Neither
This fossil snake and this living rat both have a structure in their skull called the quadrate bone. How did this happen?
The snake and rat are different species, so they are related. They inherited the quadrate bone structure from separate ancestors.
ll species have their own specific body structures, so it is just a coincidence.
The snake and rat both share the same ancestor population that had a quadrate bone.
It is impossible to say. Fossils are very old.
This octopus and this surf clam both have a body structure called a mantle, which covers their soft bodies. However, the octopus’s mantle has muscles that help the octopus swim. The surf clam’s mantle helps the clam build its shell. Why are the mantles different?
All species have their own specific body structures, so it is just a coincidence
The octopus and surf clam are different species, so they do not share an ancestor population.
It is impossible to explain the body structures of different species
The octopus and surf clam both inherited the mantle structure from a shared ancestor population.
an older population from which two or more newer species descended or evolved from.

descendent species
a body structure in two or more species that has the same parts (for example, the same bones).

How does the study of evolutionary history benefit from the amplification of ancient DNA?
It allows for the reconstruction of extinct species' genomes
It speeds up the process of natural selection
It helps in the creation of genetically modified organisms
It provides a method for cloning ancient species

In the context of evolutionary history, what does the term 'amplify' refer to?
Increasing the number of copies of a DNA segment
Enhancing the physical traits of an organism
Accelerating the process of evolution
Expanding the habitat of a species
Which of the following experiments would help in amplifying evolutionary history?
Using PCR to replicate ancient DNA samples
Breeding organisms in controlled environments
Observing natural selection in real-time
Simulating environmental changes in a lab
What role does the Polymerase Chain Reaction (PCR) play in studying evolutionary history?
It helps in identifying genetic mutations
It amplifies specific DNA sequences for analysis
It measures the rate of evolutionary change
It sequences entire genomes
Why is it important to amplify DNA when studying evolutionary history?
To ensure there is enough material for analysis
To increase the genetic diversity of a sample
To speed up the evolutionary process
To create new species in the lab
