Do Humans Share DNA with Plants?

Published in Genetics and Evolution 1 min read

Yes, humans do share DNA with plants.

While it might seem surprising, a significant portion of human genes are also found in plants. According to the information provided, 20-60% of human genes can be found in plants, depending on the specific plant species.

Here's a quick breakdown:

Comparison Gene Similarity
Humans and Plants 20-60%
Humans and Mice ~80%
Humans and Chimpanzees ~95%

The genes shared between humans and plants often relate to fundamental processes. Specifically, many of these shared genes are involved in:

  • Turning sugars into energy
  • Converting proteins into energy

This demonstrates that despite the vast differences in appearance and lifestyle, humans and plants have a shared ancestry and some common genetic mechanisms. This shared heritage is most notable in the most basic cellular and metabolic processes.
