IQ3: Theory of Evolution by Natural Selection
#
Accumulation of Microevolution
Macroevolution
e.g. Horse
Number of Digits
Teeth Size & Shape
Size of Organism Increased
Environment
Over 50 millions Years
Type of Evidence
Transitional Fossils
Millions of Years
Results in new Species
Shorter Periods
No Speciation
New Variaitons
Types of Evolution
Divergent
Recent Common Ancestor
Adaptive Radiation
E.g.
Convergent
Same Environment (selection pressures)
Homologous Structures
E.g. Dolphins & Sharks
Punctuated Equilibrium vs, Gradualism
IQ4: Evidence of Evolution
Homogolous
