Long ago, when humans first started to name organisms, every group of people had a different name for the same living thing. Many years later, scientists fixed this problem by giving every living thing a scientific name that would be known worldwide. For example, in English we call a certain bird a "bald eagle." In Spanish, the same bird is called "águila calva." However, scientists around the world know the bird by its scientific name: Haliaeetus leucocephalus.
Why is assigning scientific names to living things important?
a
It prevents scientists from using the same organisms to replicate experiments.
b
It stops the use of common names like "bald eagle" and "águila calva."
c
It helps identify where the living thing was first found in the world.
d
It helps scientists identify the same living thing, even in a different language.
