Evidence of Evolution

Fossils

• Formation of new species caused by reproductive isolation
• examples of vestigial structures
• The preserved remains or traces of organisms that once lived on Earth.
• Have the same function but different structure, is usually seen in convergent evolution

homologous structures

• similar structures that related species have inherited from a common ancestor
• Formation of new species caused by reproductive isolation
• Have the same function but different structure, is usually seen in convergent evolution
• The theory that evolution occurs slowly but steadily

morphology (evolution)

• 4. Comparative embryology
• Have the same function but different structure, is usually seen in convergent evolution
• Formation of new species caused by reproductive isolation
• the branch of biology that deals with the forms of living organisms and with the relationships between their structures

vestigial structures

• similar structures that related species have inherited from a common ancestor
• remnant of a structure that may have had an important function in a species' ancestors, but has no clear function in the modern species.
• main example of coevolution
• Study of past and present distribution of organisms that can be used to determine common ancestry

evidence for evolution

• Comparative biochemistry

• examples of homologous structures
• Fossil Record

• evolved due to convergent evolution

Comparative anatomy (morphology)

• Pattern of evolution in which long stable periods are interrupted by brief periods of more rapid change
• the study of the formation, early growth, and development of different organisms to determine possible common ancestry
• Have the same function but different structure, is usually seen in convergent evolution
• 2. Comparative anatomy (morphology)

Comparative biochemistry

• Comparative biochemistry

• Have the same function but different structure, is usually seen in convergent evolution
• An evolutionary pattern in which many species evolve from a single ancestral species
• remnant of a structure that may have had an important function in a species' ancestors, but has no clear function in the modern species.

4. Comparative embryology

• examples of vestigial structures
• the study of the formation, early growth, and development of different organisms to determine possible common ancestry
