EVIDENCE FOR EVOLUTION


1. Anatomical structures (fossil records)

• Comparative Anatomy

• Homologous and analogous structures

• Vestigial structure

2. Comparative Embryology

3. DNA sequences (Biochemical)

1. ANATOMICAL STRUCTURES

• Part of a body

FOSSIL RECORD

• History of life documented by fossils

• Fossil record represents less than 1% of all species that ever lived

COMPARATIVE ANATOMY

• Study of similarities and differences of the anatomies of different organisms

HOMOLOGOUS STRUCTURES

• Structures inherited from the same ancestor; variation in use

QUICK CHECK

• Do homologous structures arise from convergent or divergent evolution?

ANALOGOUS STRUCTURE

• Different anatomies (from different ancestors) but similar functions

QUICK CHECK

• Do analogous structures arise from convergent or divergent evolution?

VESTIGIAL STRUCTURE

• Anatomical structure that was important to an ancestor, but no longer serves a purpose

2. COMPARATIVE EMBRYOLOGY

• Comparing embryos of species

• Embryo = unborn offspring in the process of development

3. DNA SEQUENCES (BIOCHEMICAL)

• Comparing DNA and genes


1. Anatomical structures (fossil records)

• Comparative Anatomy

• Homologous and analogous structures

• Vestigial structure

2. Comparative Embryology

3. DNA sequences (biochemical)
