Ancient DNA analysis involves extracting and sequencing genetic material from preserved plant remains to study organisms from the past. This technique is valuable for plant science as it reveals the genetic changes that occurred during crop domestication and provides direct molecular evidence of how cultivated plants evolved from wild ancestors. By understanding these genetic transitions, researchers can trace the origins of agriculture and how plants adapted to human cultivation.
