Patterns of Evolution

Occurs when different organisms that live in similar environments become more alike in appearance and behavior because the environment selects similar adaptations in unrelated species.

• Divergent Evolution

• Adaptive Radiation

• Convergent Evolution

• Disruptive Selection

Evolution with a pattern of long, stable periods interrupted by brief periods of rapid change

• Punctuated Equillibrium

• Co-evolution

• Speciation

• Balanced Speciation

When selection occurs for one extreme trait.

• Directional Selection

• Disruptive Selection

• Stabilizing Selection

Type of selection that favors average traits.

• Directional Selection

• Disruptive Selection

• Stabilizing Selection

What is the best inference about biochemical relationships that could be made from this model?

• The amino acid sequences of a lancelet and a tuna are more similar than that of a tuna and a salamander. This is due to the lancelet and the tuna both residing entirely in water while the salamander can survive on land.

• The amino acid sequences of a salamander and a turtle are less similar than that of a turtle and a leopard. This is due to the turtle and the salamander both being adapted to life in water or land.

• The amino acid sequences of a lancelet and a tuna are less similar than that of a tuna and a salamander. This is due to the lancelet and the tuna splitting from a common ancestor longer ago.

• The amino acid sequences of a salamander and a turtle are more similar than that of a turtle and a leopard. This is due to the turtle and the salamander both being adapted to life in water or land.
