👉 Heterogamy is a concept in evolutionary biology that describes how different species evolve and adapt to their environments. It refers to the fact that two or more species of organisms, such as humans and dogs, may be genetically identical but have distinct physical characteristics and behaviors. In other words, heterogamy means that two or more species are not related by natural selection alone and can potentially coexist with each other without interacting in any way. This is different from sexual reproduction, which allows for genetic variation
