See Ms. Johnson
Biogeography: Study of the distribution of
species geographically and historically, and why (or
why not) they are found in a geographical area.
• Look at page 383 in your text.
• What land is shared by two rodent species?
• Why do you think rodent species in the
Americas are divided into different ranges?
or 832
Fossil Record: Groupings of fossilzed
organisms used to provide evidence
about Earth’s history.
Comparative Anatomy: Homologous
structures in different organisms show
common ancestors.
Comparative Embryology: Early stages
of embryos show similarities.
For each step of guess the embryo, write down on
scratch paper which one you think will will.
Molecular Biology: Genetic
mapping to show DNA
connections between organisms.
Red Panda: Related to Racoon, Bear or Panda?

• (10 January 2010, Brazil) An electrical discharge
made toast of municipal guard Arthur de Souza
Coelho, 47, on Sunday evening.
• According to police reports, he had installed a tiny
electric fence around his car to protect against the
frequent robberies that occur in his neighborhood
in Belem, Para. Then (direct translation from
Portuguese) "he forgot that he had left the fence
on and he ended dying with the electric shock.”
• After all, we are all dying, but some end sooner
than others.
Reflection:
Give an example of one of these 5
sources of evidence for evolution:
•Biogeography
•Fossil Record
•Comparative Anatomy
•Comparative Embryology
•Molecular Biology (DNA)
