Question

Matching the following terms and definitions.

1.adaptive radiation
2.coevolution
3.convergent evolution
4.divergent evolution
5.gradualism
6. punctuated equilibrium


a pattern of evolution in which two species evolve in relation to each other
a pattern of evolution in which similar characteristics evolve between two unrelated species
a theory of evolution that states that a species evolves by consistent, small, steps
a pattern of evolution in which very different species evolve from one common ancestor
a theory of evolution that states that a species evolves in spurts of rapid change and then no change
a pattern of evolution in which slightly different species evolve from one common ancestor

Answer 1

• Adaptive radiation - a pattern of evolution in which slightly different species evolve from one common ancestor

For example - Evolution of mammals after the extinction of dinosaurs.

• Co evolution - a pattern of evolution in which two species evolve in relation to each other

For example – Development of flowering plant and associated insects or pollinators

• Convergent evolution - a pattern of evolution in which similar characteristics evolve between two unrelated species

For example – similar function of flight or wings of insects, birds and bats

• Divergent evolution - a pattern of evolution in which very different species evolve from one common ancestor

For example – different types of beaks of finches

• Gradualism - a theory of evolution that states that a species evolves by consistent, small, steps

For example – evolution of tigers to develop better line marks on their body

• Punctuated equilibrium - a theory of evolution that states that a species evolves in spurts of rapid change and then no change

Answer 2

1. Adaptive radiation: A pattern of evolution in which slightly different species evolve from one common ancestor.

2. Coevolution: A pattern of evolution in which two species evolve in relation to each other.

3. Convergent evolution: A pattern of evolution in which similar characteristics evolve between two unrelated species.

4. Divergent evolution: A pattern of evolution in which very different species evolve from one common ancestor.

5. Gradualism: A theory of evolution that states that a species evolves by consistent, small, steps.

6. Punctuated equilibrium: A theory of evolution that states that a species evolves in spurts of rapid change and then no change.
