BD#14 Divergent Evolution

What is divergent evolution?

• A concept where organisms do not evolve

• A process where organisms from a common ancestor develop different traits due to different selection pressures

• A theory that all organisms have a common ancestor

• A process where unrelated organisms develop similar traits

Who contributed to the theory of evolution by natural selection?

• Mendel and Morgan

• Watson and Crick

• Hawking and Einstein

• Darwin and Wallace

What does the pentadactyl limb demonstrate?

• Convergent evolution

• Divergent evolution indicating common ancestry

• The presence of analogous structures

• The lack of evolutionary change

What are homologous structures an indication of?

• Analogous structures

• Independent evolution

• Convergent evolution

• Common ancestry

What is NOT a characteristic of divergent evolution?

• Adaptive radiation

• Common ancestry

• Unrelated organisms developing similar traits

• Different traits due to selection pressures

What are analogous structures?

• Structures in different species with a common function but not a common ancestry

• Structures that are present in all living organisms

• Structures that do not evolve

• Structures that indicate common ancestry

What does adaptive radiation refer to?

• The convergence of similar traits in unrelated species

• A type of radiation used in adaptive technologies

• The process where organisms spread into various environments and evolve differently

• The emission of radiation by all living organisms

What is the significance of the pentadactyl limb in mammals?

• It shows a common organizational plan suggesting common ancestry

• It proves that mammals are the dominant species on Earth

• It is used to determine the age of mammals

• It indicates that mammals can fly

What is the primary difference between analogs and homologs?

• Analogs are found only in mammals, while homologs are found in all organisms

• Analogs indicate common ancestry, while homologs do not

• Homologs indicate common ancestry, while analogs do not

• There is no difference; they are the same

Which of the following best describes the concept of divergent evolution?

• It is the process by which new species are created

• It describes how species with a common ancestor can evolve to look similar

• It explains how species with a common ancestor can evolve different traits

• It is a concept that has been disproved by modern science
