MECHANISMS OF MACROEVOLUTION
List the Mechanisms of Macroevolution
Continental Drift
Give two causes and evidence for mass extinction with specific examples.
List the causes of adaptive radiation with examples of each.
EVO-DEVO
Small genetic changes create large morphological changes.
list four examples and explain how the change comes about
Changes in rate and timing: explain paedomorphism
Changes in Spatial pattern: explain evolution of tetrapods from fish
New genes and changes in genes: explain duplication of genes followed by mutation of extra copies
Changes in gene regulation: homeotic gene expression or non-expression as a mechanism of evolutionary change.
Describe the nature of evolutionary trends.
What is parsimony in relation to phylogenic trees?
