True or False: Biological evidence only includes items with recoverable DNA.

The assertion that biological evidence only includes items with recoverable DNA is false. Biological evidence encompasses a wide range of materials that can provide insights into the circumstances surrounding a crime, and it is not limited solely to items containing DNA.

For instance, biological evidence can include blood, saliva, urine, hair, skin cells, and even certain types of plant materials. While DNA found in these materials can be a key focus of analysis due to its ability to uniquely identify individuals, there are many other forms of biological evidence that do not necessarily contain recoverable DNA but can still be critically important in a criminal investigation.

This might include the examination of blood types or the presence of certain biological materials that can help establish connections or exclusions within a forensic context. Additionally, some biological evidence might deteriorate or not yield DNA, yet still hold value in understanding the events that transpired. Therefore, it is important to recognize that the scope of biological evidence is broader than just items with recoverable DNA.
