Final answer:
Biological science has developed over time by building on observations and experimentation made by scientists around the world and throughout history.
Step-by-step explanation:
The statement that best describes how biological science has developed over time is: Each new idea builds on observations and experimentation made by scientists around the world and throughout time.
Science is a process that is constantly evolving and changing. Scientists build on the knowledge and discoveries of their predecessors, conducting further observations and experiments to gain a deeper understanding of the natural world. This gradual accumulation of knowledge helps refine and revise existing ideas, leading to an increasingly accurate and detailed understanding of biology.
For example, when scientists discovered how genes control genetic traits, they didn't discard Mendel's laws of inheritance but instead used the new discoveries to explain why those laws applied to certain traits but not others. This demonstrates how new ideas build on previous observations and experimentation.
