Theorists
Lamark
What is required within a population in order for natural selection to occur?
Genetic Variation
What type of speciation occurs when organisms prefer to mate at different times of the year?
Temporal
Which type of drift occurs when a variation within a population is reduced because of a catastrophic event?
Bottle neck
The out group on a cladogram has the __________ number of shared derived traits
What is the name of the scientist who developed the idea that the organisms with the best adaptations survive to reproduce within the population
Darwin
The organisms who is most fit will ______________ and _______________.
Survive and reproduce
What type of selection occurs when organisms are attracted to different types of mating songs? Like birds
Behavioral
What type of drift occurs when genetic variation is reduced because part of the population moves to a new location?
Founder effect
A common ancestor
What is the name of the theory that explains how organisms with the best adaptations survive to reproduce
Survival of the Fittest
Which type of selection occurs when the average genotype of a population shift to on extreme?
Directional
A population of moles is divided when a new highway is built through their environment. This leads to the populations developing different adaptations. What type of speciation is this?
Geographical
A hurricane destroys most of the population of rat snakes living the in forest. This leads to reduced genetic variation within the population. What type of drift occured?
Bottle neck
See picture #3. Which organism has the most derived characteristics?
Cat
A squirrel needed to develop wing-like arms to be able to fly from tree to tree to get away from predators. It was able to grow these additions to its arms within its lifetime. What is the name of the theory that explains this type of evolution?
Inheritance of acquired traits
See picture 1. What type of selection is represented?
Stabilizing
An albino peahen was hatched and matured to prefer the mating dance of other albino peacocks only. This developed into a new population of peacocks who are albino and only prefer the mating dance of other albino birds. What type of speciation is this?
Humans from the U.S. found an insect in Asia that was able to reduce the population of mosquitoes. They brought a few members of this population to the U.S. What type of genetic drift occured?
Founder effect
See picture #3. What traits does the horse have?
Hair
What is the name of the islands that are home to the finches that were studied by the main evolutionary biologist?
Galapagos Islands
A population of snakes lives in the rainforest. The yellow snakes are easy to spot by predators. The brown snakes blend in well with the ground. The green snakes blend in well with the trees. What type of selection is this?
Disruptive
Prezygotic
See picture #2. What type of genetic drift is occurring?
Founder effect
