Which field of study does forensic biology encompass?

Forensic biology encompasses the study of living organisms within a forensic context, focusing on cellular, microbiological, and other biological aspects that can be relevant to criminal investigations. This includes collecting and analyzing biological evidence such as blood, hair, bodily fluids, and plant material to assist in solving crimes. By examining these biological components, forensic biologists can provide crucial information that helps establish links between evidence and individuals, determine the cause of death, and contribute to the broader understanding of the events that transpired at a crime scene.

The other fields mentioned, while important in their own rights, do not align with the specific focus of forensic biology. The study of fossils and ancient life pertains more to paleontology. Analyzing human behaviors in crime falls under criminology or psychology rather than biology. Lastly, while the study of plant life has forensic applications, it is a narrower scope compared to the broad biological aspects included in forensic biology. Thus, the choice that best represents the encompassing nature of forensic biology is the study of life, including aspects of cellular and microbiology.
