"DNA"

Theoretically, life can take many different forms, such as silicon-based life, sulphur-based life, carbon-based life, amino-life, hydrogen-based life, etc. However, so far we only know that life exists on earth, and all known life, including us humans, is carbon-based.

This phenomenon could not be detected through traditional dietary research methods, but by using DNA-based techniques, such interactions were revealed for the first time, leading to important questions about how human activities affect wildlife.
