Question

a) How are the studies of anatomical structures helpful for tracing evolutionary

relationships?



b) How could we determine that ‘the birds are very closely related to reptiles’?​

Answer 1

Answer:

• The anatomical structures and physiological functions of different species provide evidence of evolution. Scientists compare and contrast types of anatomical features, known as homologous structures, vestigial structures, and analogous structures, to figure out how closely related different organisms are.
