transitional form
Give this one a try later!
exhibit intermediate characteristics between ancestral form and
descendants
evolution
Give this one a try later!
changes in populations from one generation to the next (over time and
happens in 1 or more heritable characteristics) and results in differential
survive and reproduction (fitness)-some individuals have higher fitness than
others
, developmental homologies (embryos)
Give this one a try later!
similarities during embryonic development (not observed/present at birth)
humans - gill ridges, bony tail
molecular homologies
Give this one a try later!
similarities in:
-use DNA as hereditary molecule
-universal genetic code
-in eukaryotes processes (cellular respiration)
-sequences of genes (DNA) and protein
convergent traits
(common characteristics = analogous structures/traits)
Give this one a try later!
similarities between species of non closely related species (different
lineages) due to similar environments
fossil record
