Variation and Adaptation
Darwin and his Theory
Tracking Changes
Origin of Species
Population Genetics
100
This is an interbreeding population of organisms that can produce healthy fertile offspring.
What is a species?
100
This scientist was the first to use the term evolution.
Who is Charles Bonnet?
100
This is the study of the early stages of an organism’s development.
What is embryology?
100
The hummingbird and flower are an example of this type of evolution.
What is coevolution?
100
The combined genetic material of all members of this classroom is an example of this.
What is a gene pool?
200
The differences between individual members of a population. An example would be different hunting techniques of spiders.
What is variation?
200
Lamarck stated that once a structure is modified by use, the modification is inherited by the organism’s offspring. This is known as what?
What is Inheritance of Acquired Features?
200
These types of structures are inherited but reduced in size and in function and not used.
What is a vestigial structure?
200
Polar bears and the brown bear are examples of this type of evolution?
What is divergent?
200
If a population is not evolving, then the allele frequency is stable. This population is following what principle?
What is Hardy-Weinberg principle?
300
An inherited trait that increases a population’s chances of survival and reproduction in a particular environment.
What is an adaptation?
300
This theory is defined as a process that shapes organisms adaptations.
What is Natural Selection?
300
Scientists use these to help reveal the relationships between species and how their structures change over time.
What is fossils?
300
Mountain Ranges, Bodies of Water, and Canyon Deserts can all cause this.
What is isolation?
300
Evolution is only measured in terms of this...not individuals.
What is populations?
400
Where an organism lives, what they eat, how they raise offspring, what their predators are all factors of this.
What is a niche?
400
This type of variation improves an organisms ability to function and reproduce in its own particular environment.
What is a favorable variation?
400
The human arm, a horse leg and a bat wing are all examples of this kind of structure.
What is a homologous structure?
400
When species with different ancestors develop similar traits is this type of evolution?
What is convergent?
400
Random events such as a natural disaster or migration cause random changes in allele frequencies. This is known as what?
What is genetic drift?
500
Inherited variation is the result of these two random processes.
What is mutation and recombination?
500
This theory states that small genetic changes occur slowly within a population.
What is gradualism?
500
These have similar functions but different structures.
What is an analogous structure?
500
The evolution of many diversely adapted species from one common ancestor.
What is adaptive radiation?
500
The example of a new born baby's weight is an example of this type of selection/distribution.
What is stabilizing/ normal?
