What is comparative embryology and what does this tell us about evolution?
a) The study of how organisms develop from fertilized eggs; it can tell us about common ancestry and evolutionary relationships
b) The comparison of embryos at different stages of development; it can tell us about convergent evolution and adaptive radiation
c) The examination of adult structures in different species; it can tell us about developmental pathways and genetic mutations
d) The analysis of gene expression patterns during embryonic development; it can tell us about regulatory networks and evolutionary constraints
