1. Scientific Methoda.
Reasoningb. Process

Experimental variables:
i. Independent =
tested for or manipulated
ii. Dependent =
changes due to Independent
iii. Control =
held constant

III. Characteristics of AnimalsA. Shared
Characteristics
multi-cellular heterotrophs, contractile proteins, special tissues, stages of development, motile, and fixed adult size
IV. Evidence of SelectionA. Fossil
Record
The fossil record is based on what three key points of data to age identify them? Strata
Positioning&Half-Life
Dating Racemization
Magnetic Reversal
B. Comparative Anatomy
Analogous structures =
Outward similar inward different or same function different structure
Figure 1.21
Homologous Structures =
Outward different inward similar or same structure different function
Vestigial Structures =
Outwardly useless remnants??

C. Comparative Embryology
Similarities in developmental patterns in animals

D. Molecular Homology
Homologies between species (yeast, wheat, & primate) in the sequential amino acid make-up of cytochrome C3.
E. Current Evidence1. Artificial
Selection
That’s all for now folks.
