Presentation transcript:

Evidence for Evolution Area: Embryology Examples: embryo of pig and human Pro: best evidence because it is the most fundamental or basic information Vocabulary: embryo — early stages of developing plants and animals comparative embryology — study of different developing organisms.

Comparative Embryology

Comparative Embryology

Evidence for Evolution Area: Biochemistry Examples: amino acid sequence of chimpanzee and human Con: limited access to amino acids of past organisms Vocabulary: comparative biochemistry — comparing amino acid sequences of different organisms

Chromosome comparison Human (H) Chimp (C)

Chromosomes of Primates Human (H) Gorilla (G) Chimp (C) Orangutan (O)

Amino Acid Sequence for Hemoglobin Molecule

Evidence for Evolution Area: Genetics Examples: domesticated plants and animals; DNA sequence; mutations Pro: changes easily seen in domestic plants/animals; gene links for generation after generation documented. Con: limited access to past DNA Vocabulary: population — all organisms within a breeding group. selective breeding — artificial selection of only the most desirable traits to be bred.
