A catastrophe kills many individuals in a population, leaving a small number of individuals to interbreed. These individuals may have different genes than the original population. This is an example of this concept in Genetic Drift.
What is Bottle Neck Effect?
100
Competition can be described as "Survival of the __________________"
What is fittest?
100
Fill in the blanks with either Homologous or Analogous:
Species that are _______________ share a common ancestor while species that are _________________ do not share a common ancestor.
What is (1) Homologous, (2)Analogous?
100
What is Sharks?
100
Male lions defend their territory for exclusive rights to mate with females in their area
What is Competition?
200
A change in the genes of a population by random chance, making a particular allele more or less common in the population.
What is Genetic Drift?
200
A mechanism by which individuals that have inherited beneficial adaptations show differential reproductive success. Therefore, in nature, characteristics are selected only if they give advantages to individuals in the environment
What is Natural Selection?
200
What is Analogous Structure?
200
What is Crocodiles?
200
The scientist who discovered natural selection as a primary source of evolution.
Who is Charles Darwin?
300
When a small group of founding individuals colonize a new location, reduced genetic diversity usually occurs.
What is Founders Effect?
300
This is the species that Charles Darwin studied their beaks on the Galapagos Islands.
What are Finches?
300
What is Homologous Structure?
300
These animals do not have Amniotic Membranes.
What are Lampreys, Sharks, and Newts?
300
A branching diagram showing the relationship between a number of species and that they all relate to a common ancestor.
What is a Cladogram?
400
Sometimes, a disaster, such as a disease or hurricane, can kill many individuals in a population.
Just by chance, the smaller, leftover or surviving population’s gene pool can be different from the original population’s.
What is Bottle Neck Effect?
400
Camouflage allows many species to blend in to their environment. Those individuals with the best camouflage are not eaten by predators as often as those with poorer camouflage. This is an example of this concept in Natural Selection.
What is competition?
400
Humans have a tail bone that they do not use/need. Whales have a hind leg that they do not use/need.
What are Vestigial Structures?
400
This species is least related to Amphibians.
What are Primates?
400
Resources such as food, water, and shelter were natural limits to population growth.
What is competition?
500
When Christopher Columbus came to the Americas, he randomly chose 3 chickens from Spain to bring along. These 3 chickens were the only chickens to breed in the Americas for hundreds of years.
What is Founders Effect?
500
Lineage-splitting event that produces two or more separate species out of the same species mostly caused by adaptions or catastrophic events over time.
What is Speciation?
500
Comparison between structures of anatomy in different organisms
What is Comparative Anatomy?
500
This species descended the longest ago.
What are Lancelets?
500
One of these is genetic variation by chance, while the other is genetic variation by adaptations for survival.
What is the difference between Genetic Drift and Natural Selection?
