History of Evolutionary Theory
I. ARISTOTLE- SYSTEMIC BIOLOGY
a. ORGANISMS RANKED FROM NON-LIVING TO HUMAN KIND
b. ORGANISMS ARE IN UN-CHANGING CLASSES
c. COMBINED WITH CREATION THEORY- ALL CREATED
II. LINNE’ (Linneaus)- 1707-78: TOOK ORGANISMS FROM ‘GOD’S SHELF”

DARWIN WROTE BOOK (1859)- ON THE ORIGIN OF SPECIES BY MEANS OF NATURAL SELECTION
IDENTIFIED EVOLUTION AS “NON-GODLIKE”
GRADUALISM- SLOW STEADY CHANGE OVER TIME BASED ON ENVIRONMENTAL NEED, EVOLUTION NOT PUNCUATED
PUNCTUATED EQUILIBRIUM- CHANGES OCCUR IN SHORT PERIODS OF TIME, THEN STAY CONSTANT FOR LONG PERIODS.
SEXUAL SELECTION- CHARMING CHARACTERISTICS OF THE SEXES ARE PASSED ON FROM GENERATION TO GENERATION
EX: DEER ANTLERS, BIRD FEATHER PATTERNS, LION MANE
V. WEISMANN- 1834-1914 MOUSE STUDY
a. CUT TAILS OFF MICE AND MATED THEM
b. 22 GENERATIONS, NO SHORT TAILS
c. DISPROVED LAMARACK’S THEORY OF ACQUIRED TRAITS
d. SUPPORTED DARWIN’S NATURAL SELECTION THEORY
WEISMANN’S WORK LEAD TO NEO DARWINISM- SLOW STEADY CHANGE OVER TIME
EVIDENCE FOR EVOLUTION IN THE FOSSIL RECORD
HOMOLOGOUS STRUCTURES- SIMILAR ANCESTORS, DIFFERENT FUNCTION
ANALOGOUS STRUCTURES- DIFFERENT ANCESTORS, SIMILAR FUNCTION
