Which kind of trait: a leopard's paw and a lion's paw
Homologous
What is the difference between microevolution and macroevolution?
Micro is over shorter time, macro is over a longer time
Macroevolution is also called the theory of evolution, while microevolution is the observable, recorded changes in species.
What is "evidence"?
Facts that can be used to support a conclusion
Which organisms are thought to be more closely related: chicken, hawk, human
Chicken and a hawk (both are birds)
Which kind of trait: whale pelvis bones
vestigial
Which kind of evolution: we have hundreds of breeds of dogs (195 according to the AKC, 339 according to the FCI)
Adaptive Radiation
