Evolution of Development
Chapter 25
The Evolutionary Paradox
Diverse morphologies are regulated by highly conserved genes.
Example, the Hox genes
Developmental changes can lead to evolutionary changes
Heterochrony
Homeosis
Changes in transcription factors
Changes in signaling pathways
One or Two Gene Mutations, New Form
The Brassica Example
Same Gene, New Function
Pitx1 and the Sticklebacks
Different Genes, Convergent Function
Homeoplastic structures
Gene Duplication and Divergence
Morning glories and pigment
Diversity of the Eyes
