15. Comparative Anatomy
Essential Question: How does the evidence of geology, fossils, and comparative anatomy support the theory of evolution?
Learning Target: I can compare and contrast fossils of several different species. I can compare the anatomy and development of several different species.
Learning Task: I will explain how evidence from comparative anatomy can be used to support evolution.

Welcome! Warm Up Friday 4/25/14 Week of 4/21 – 4/25
Darwin observed many birds that had many different beak shapes and sizes. There a were few beaks that were similar because of…
a. competition for the same type of food
b. competition for a specific concentration of oxygen in the atmosphere
c. the presence of an excessive number of autotrophs
d. the presence of a disease that attacks birds with similar beaks

Evidences for Evolution
So far, we have talked about evolution and the processes that drive it (natural selection).
But how do we know that evolution occurs?
There are three major evidences that we are going to evaluate:

I. Morphological Evidence (Comparative Anatomy):
Comparing physical structures among organisms
![Page 9: 15. Comparative Anatomy Essential Question: How does the evidence of geology, fossils, and comparative anatomy support the theory of evolution? Learning.](https://reader035.fdocuments.net/reader035/viewer/2022062421/56649e5e5503460f94b57229/html5/thumbnails/9.jpg)
A. Homologous Structures1. Definition:
Structures that have common ancestry. Structures are similar; function may or may not be different.
2. Example: human arm, whale flipper, dog front leg, bat wing, bird wing

B. Analogous Structures1. Definition: Different structures with
similar function in organisms are NOT closely related, but are adapted to the same environment.
2. Example:
Dolphin fin (class: mammal) made of bones;
Shark fin (class: cartilaginous fish) made of cartilage

C. Vestigial Structures
1. Definition: Structures reduced in size because they serve no apparent purpose
2. Example: Whale pelvis, Snake pelvis, Human tail bone, appendix, wisdom teeth

II. Similar Embryology (Comparative Embryology):
A. Definition: Comparing embryos of related organisms
They look similar, but get more different as they develop
B. Example: Vertebrate embryos (including humans) have gill slits, tails, and limb buds…but eventually the gill slits and tails may be lost

III. Biochemical Evidence
A. REMEMBER: DNA codes for proteins
B. Definition: Comparing DNA to determine organisms’ evolutionary past
Similarity in DNA = relatedness b/w organisms
C. Example: Human & gorilla have more DNA in common than human & fish, so human & gorilla are more related
