Breeding of strawberries in water where other fish would freeze to death but, with a special gene that allows it to produce a sort of anti-freeze, it can survive. This gene is put into a bacteria that is sprayed on the strawberry during the freezing temperatures, allowing it to also be resistant to cold. The strawberry is then cleaned, removing the bacteria. Breeding of strawberries The breeding of strawberries is a long story that starts with the selection and cultivation of European strawberry species in western Europe in the 15th century while a similar discovery and cultivation occurred in Chile.

Cooperative breeding an evolutionary model for cooperative breeding, which linked the coevolution of polytocy, production of multiple offspring, and monotocy, production of single offspring, with the evolution of cooperative breeding. The model is based on the evolution of larger litters forcing the need for helpers to maintain the high reproductive costs, thus leading to cooperative breeding. Lukas et al. suggests polytocy may have encouraged the evolution of cooperative breeding. Their proposed model suggests the transition from monotocy to polytocy is favorable. Additionally, they found the transition from polytocy without cooperative breeding to polytocy with cooperative breeding is highly favorable. This suggests cooperative
