•  The results of the study of the brain of insects during metamorphosis are the most detailed. 

•  Insect metamorphosis evolved to reduce competition for resources between adults and offspring. 

•  Metamorphosis began about 350 million years ago, before the advent of dinosaurs. 

•  Metamorphosis affects the brain of insects, which undergoes significant changes. 

•  During metamorphosis, the insect brain recycles most of the neurons to function again. 

•  Metamorphosis changes connections between neurons, destroying old ones and creating new ones. 

•  Memories of a larva cannot be stored in the brain of an adult insect. 

•  Associative memories can be associated with smells and direct insects to or away from something. 

That sounds like what happens when I’m having an orgasm.
