Venomous fangs evolved independently in vipers and cobras

U of A biology grads shed new light on the evolution of an iconic feature of some modern snakes

Insects reduce their functions so only essential processes work: respiration and waste elimination

When it gets cold, where do all the bugs go?I know it’s still summer but soon it will get colder and things will be radically different. Sometimes I wonder where all the bugs go in the winter.
