Peptides are short chains of ammino acids that contribute to a diversity of crucial functions within the human body. Anti-microbial peptides halt the growth of pathogenic cells and therefore play a critically significant role in the immunological activities of many organisms including both humans and amphibians.
Amphibian populations around the world have declined due to the chytrid fungus (Batrachochytrium dendrobatidis). Recently, University College London researchers studied midwife toads within four lake ecosystems within the Pyrenees of France and Spain. All four lakes experienced brutal chytrid fungus outbreaks. It was discovered that toads from populations recovering from chytrid fungus outbreaks are using an incredible defensive mechanism: they are releasing protective peptides from their skin as tadpoles. In contrast, toad populations that are struggling to recover from chytrid fundus outbreaks are producing fewer protective peptides during the tadpole stage of their development. The research uncovered an incredible amount of previously unknown protective peptides: of the 1,152 peptides identified, only seven had already been documented.

Natural ecosystems are rich providers of brilliant chemical technology. By performing scientific research within natural ecosystems rather than in laboratories, scientists can discover chemical defense mechanisms that respond to natural survival challenges rather than artificial environments. The result is that natural ecosystems are incredible resources for uncovering new biochemical discoveries. Furthermore, both the similarities and the differences between humans and other animals allow for wild animals to be a source of biochemical innovation.
Responsibility challenges emerge as soon as corporations try to establish IP rights over biochemical discoveries that emerge more from nature than from human ingenuity. If a new drug is mostly modeled after chemical defense mechanisms discovered within nature, does it make sense for only one corporation to claim the right to use that intellectual property? Furthermore, if that IP is not expanded upon with creative freedom from other corporations, then this may hold back the progress of biochemical innovation resulting in patients not receiving the treatments that they need to survive. Although IP rights are incredibly important for ensuring that innovators benefit from the fruits of their labor, IP rights must be balanced with the societal need for beneficial rapid innovation. And when it comes to life saving medical innovation, it is especially important that such discoveries are made universally available as quickly as possible.
