Answer:
The transfer of energy through empty space is called convection.
Explanation:
One of the fundamental laws of the universe is the conservation of energy. Energy can't be created and it can't be destroyed. Convection can be the process by which heat is transferred . Temperature is known as  the basic principle of heat transfer. The amount  that how much of thermal energy can be available is determined by the temperature, and the heat flow represents movement of thermal energy.

A biologist would most likely concentrate on homologous features to find and analyse an evolutionary relationship between two species, finding homologous traits between species might help biologists to understand the evolution of animals, whereas concentrating on analogous features might help to compare the evolution of different species. Hope this helped!
