1. Day 1: Developmental
Biologists
Ms. Liu
Biology
10/3/11

2. Vocabulary: Triple Journal Entry
• Embryology – The study of early
developmental biology before an organism
is born or hatched
• Embryo – Prebirth stage of developing
organism
• Vertebrates – Animals with a
backbone/spine

3. Deoxyribonucleic Acid (DNA)
• DNA IS THE CODE FOR LIFE!!!!
• It is unique and different for everyone,
every species, and every different type of
cell

4. DNA Comparison
How similar is the DNA of
hemoglobin in humans vs. primates?
• Calculate:
% similar = (# DNA bases same) x 100
total # DNA bases (60)
***Make sure you know this equation!

5. Homework:
• On last page, calculate the % similar for
the DNA of:
1) Human vs. chimpanzee
2) Human vs. gorilla
3) Human vs. orangutan

6. Day 2: Physical Anthropologist
10/4/11

7. Physical Anthropology
• The study of evolutionary history
of humans and our closest
relatives, non human primates
and hominids

8. Day 3: Paleontologists
10/5/11

9. Vocabulary
• Paleontology - The study of fossils and
the history of life (to understand geological
and biological change!)
• Stratigraphy – Indirect method of dating
rocks and fossils
• Strata – Layers of earth

10. Strata

11. Questions
• Which strata is the oldest? The youngest?
• Where will you find each fossil type in the strata?
What can you infer about the location of the
fossils?
• Look at the similarities and differences between
the fossils. What can you tell about their
evolution?
• (Pay close attention to the foot, size, and spine

12. Day 4: Evolutionary
Biologists
10/6/11

13. Evolutionary biology
• The study of the evolution of inherited
traits, such as appendages, and how they
changed over time

14. Homologous Structures
• Compare the bird wing, the bat wing, and
the human hand.
• These are HOMOLOGOUS
STRUCTURES – Structures with similar
bones that have the same use for different
organisms

15. Vestigial Structures
• Are structures have evolved over time to
be smaller and are no longer of any use.
• Basically these part have no function!
• EX: Penguin’s wings and wisdom teeth

16. In your science journals:
• Write a paragraph explaining the “inherited
traits” for the appendage bones:
• What are the similarities and differences
between our arm bone structure
compared to that of the bird and bat wing?
