GENETICS

  • Genetics support evolution
  • Mutation and reshuffling of genes increase heritable variation

3.

MOLECULES

  • Not DNA
  • Homologous proteins share similarities: structure + chemicals
  • Genetic code and homologous molecules - common descent
  • Homology is not limited to physical structures

4.

GENES

  • The genetic code is nearly identical in almost all organisms
  • Minor changes in genome -- major changes for descendants
  • Hox genes help determine embryonic development
