Transition fossils
●Transition fossils show that living things have changed gradually over time
●They show links between ancient organisms and modern organisms
Embryology
●This is the early development (EMBRYOS) of living things
●All animals pass through similar stages of development- this shows that all
vertebrates evolved from a common ancestor
DNA
●The chemical code that makes all living things unique
●DNA of different species shares some similar genes, which shows how closely related they are
(example, humans and rabbits have similar DNA codes)
●These similarities show that all mammals have a common ancestor
Similar body structures
●Also known as homologous structures
●Body structures that are similar in different species.
●Examples: bat wing/whale fin/human arm
●These similarities show that all mammals have a common ancestor
