Punctuated Equilibrium is a hypothesis that ... O suggests that evolution is not gradual but occurs in uneven pulses, where the evolution of new species can happen rapidly. O None of these answers are true O suggests evolution happens when there is a disturbance in “the force.” envisions evolution occurring through sudden changes in a gene pool. envisions evolution as a slow/gradual process.

. A population of red deer were trapped on an island off of England during the last interglacial period. Within 6,000 years, the population evolved from a mean weight of 200 kg toa mean weight of 36 kg. The generation time of red deer is 5 years and the narrow senseheritability of body weight is 0.5. What is the rate of evolutionary change (in Darwins)?

Find two cases in the media (internet, TV, etc.) of a person (organization, etc.) attempting to describe and example of the process of Darwinian evolution but is incorrectly describing the evolution process using a Lamarckian approach to evolution. Give the following information for both cases: Source (Where you found it) In what ways are they mistakenly claiming that the evolutionary process is an example of Darwinian evolution? How do you know that they are really describing evolution through a Lamarckian process, not a Darwinian process?

In the following scenario, what mechanism(s) of evolution appear to be in play? Also from what lake do you think this population may be most closely related to? What may explain how the population in A came to be here? On the Paruna River, Southern Brazil This oxbow lake (a lake formed when a section of a river is cut off) floods when the winter rains occur (call in lake A). At those times animals from the lake and river can mix. Currently it is the dry season (low water levels in the river) and no flooding has occurred for the past five years. In this lake there is a population of leaf-mimic fish. These fish spend most of the day floating on their sides, acting like dead leaves. At this time they show mainly the brown color morph (some fish are yellow, orange, red, likely to match the species of tree that surrounds the body of water). At this time the lake is surrounded by a tree that drops leaves which are brown in color. Color pattern in this fish is genetic. A few miles downriver…
