• The image shows organisms that are not closely related.

Cichlid fishes in lakes of the East African Rift. The lakes in this area are believed to support and sustain about 2,000 different species of these fish, each with different ecological and morphological characteristics such as body size. These lakes form a fragmented landscape that bio-geographically isolates the different species of cichlid fish from one another, allowing them, and many of the organisms they live with, to evolve separately.

• Phyletic Speciation

• Adaptive Radiation

• Convergent Evoltion

• Divergent Evoltuion

• Co-evolution

Which of the following processes is a new species formed by a physical barrier separating a single population into two populations?

• Coevolution
• Allopatric Speciation
• Adaptive Radiaiton
• Bottleneck

Process in which organisms diversify rapidly into a multitude of new forms, particularly when a change in the environment makes new resources available, creates new challenges, or opens new environmental niches

• Adaptive Radiation

• Geographical Isolation

• Diversification through domination

• Recessive Isolation

What was the effect of geological isolation

• A species is allowed to evolve separated from others

• Species follow the same pattern of evolution as others

• Species always die off

• Species no longer exist
