Evolution 1
The process in which a species has changed over time is known as this.
What is evolution?
Speciation requires isolation.
The type of isolation where organisms use different mating rituals
What is behavioural isolation
The ability of an individual to survive and reproduce is known as this.
What is fitness?
Theory that evolution occurs with relatively sudden periods
What is the Theory of Punctuated Equilibrium?
Tnet movement of alleles from one population to another
What is the gene flow?
The concept that members of each species compete regularly for food, space, and other necessities is known as this.
What is competition?
Physical or behavioural barriers lead to a new species forming over time.
What is speciation?
Any inherited trait that increases an organism's chance of survival is known as this.
What is an adaptation?
Observed changes within a population (from one generation to the next) due to changes in gene frequency.
What is microevolution?
The Sage Grouse females choose mates based on appearance
What is Non Random Mating?
Preserved remains of ancient organisms used by scientists as evidence to support the theory of evolution are known as this.
What are fossils?
Speciation in which populations within the same geographical areas diverge and become reproductively isolated.
What is a sympatric speciation?
The concept that organisms who are the best suited to their environment will be the most successful
What is survival of the fittest?
Closely related species become increasingly different from a common ancestor.
What is divergent evolution?
A large population is drastically reduced by disaster, disease, or human activity.
What is the bottleneck effect?
Change in the gene pool due to a random event, not evolution
What is genetic drift?
Speciation requires isolation.
The type of isolation where organisms reproduce at different times
What is temporal isolation?
The process in which nature determines which individuals/adaptations survive is known as this.
What is natural selection?
Darwin's major example of adaptive radiation happened in this location.
What is The Galapagos Islands?
Favoring of both extremes, removal of intermediates
What is disruptive selection?
This term refers to the availability of different traits and alleles within a population.
What is variation?
Speciation requires isolation.
The type of isolation where organisms are in different habitats/locations and do not interact.
What is geographic isolation?
The concept of humans selecting desired traits in species for exploitation is known as this.
What is artificial selection?
Organisms that exhibit analogous structures.
What is convergent evolution?
Island colonization by a few plants, animals, or insects (such as Hawaii, Galapagos)
What is the founder effect?
Different variations of the same gene in a population. Offspring can get two different from their parents.
What is an allele?
Two populations in an environment become geographically separated allowing them to evolve independently.
What is allopatric speciation?
Ecological role or way of life of an organism.
What is ecological niche?
Big changes result from the accumulation of many small changes over time.
What is gradualism?
Dark-colored peppered moths during industrial era.
What is directional selection?
