Evidence of evolution

What are homologous structures?

(examples include bat wings, whale flippers, and human arms)

• Structures that look the same in all species

• Structures that have a common origin but may have different functions

• Structures that are no longer useful

• Structures that have different origins but similar functions

• The tailbone

• The brain

• The lungs

How do fossils provide evidence for evolution?

• They show that all species have remained unchanged over time

• They provide a record of past organisms and show changes over time

• They only show the existence of extinct species

• They prove that all species appeared at the same time

How does embryology support the theory of evolution?

• It shows that embryos of different species look completely different

• It shows that embryos of different species look similar early in development

• It proves that all species develop in the same way

• It shows that embryos do not change over time

What are analogous structures?

(examples include insect wings, bat wings, and bird wings)

• Structures that have a common origin but different functions

• Structures that have different origins but similar functions

• Structures that are identical in all species

• Structures that are no longer useful

Which of the following is an example of a homologous structure?

(these are structures that evolved from an ancient ancestor but may have different uses now)

• The wings of a bat and the wings of a butterfly

• The flippers of a whale and the wings of a bird

• The forelimbs of a human and the forelimbs of a cat

• The eyes of a human and the eyes of a fly

Why are vestigial structures considered evidence for evolution?

• They are fully functional in all species

• They indicate that species have not changed over time

• They are remnants of structures that were functional in ancestors

• They are newly developed structures

How does comparative anatomy support the theory of evolution?

• It shows that all species have identical structures

• It shows similarities and differences in structures, indicating common ancestry

• It proves that all species have unique structures

• It demonstrates that structures do not change over time
