Distinguish homologous and analogous structures, explain their evolutionary evidence and interpret pentadactyl-limb examples.
The biological insights of Mendel and Darwin in the 19th century remain important to this day.
Describe, using one example, how homologous structures provide evidence for evolution.
| a | similar structure but different function «in homologous structures» |
| b | pentadactyl limbs/limb with five digits/toes / other example |
| c | similar bone structure/example of similarity of bones «in pentadactyl limbs» but different uses/functions |
| d | two examples of use of pentadactyl limb by a vertebrate group |
| e | suggests a common ancestor «and evolutionary divergence» |
| f | process called adaptive radiation |
