Answer:
Since the publication of Charles Darwin's On the Origin of Species in 1859, biological research has been dominated by evolutionary theory. This has led to a better understanding of how species change over time and how species interact with one another and with their environment. It has also led to an increased focus on conservation biology, which seeks to protect threatened species and manage healthy ecosystems. Research has also looked at the genetic basis of evolution and how organisms adapt to their environment. Areas such as molecular biology, genetics, and epigenetics have all been impacted by Darwin's work and have led to a better understanding of how organisms work and how they evolve.
