What do new fossils reveal about the origins of spider fangs?

Scientists found new fossils that help us understand how spider fangs started to look like they do today, kind of like finding old drawings that show how a toy car used to be shaped before it became the one you play with now.

Fossils are like time capsules. They're made when an animal or plant is buried under dirt and rocks for a very long time, sometimes millions of years! Over time, the bones (or other parts) turn into stone, keeping their shape so we can see what they looked like back then.

These new fossils showed that ancient spiders had simpler fangs. Imagine having a soft, squishy tooth instead of something sharp and pointy. These early fangs were more like little claws or hooks, not as good at piercing things as today’s spider fangs are.

As time passed, those simple fangs changed and became sharper, like how your toy car might get new wheels or a better roof over the years. This means spiders evolved to be better hunters, kind of like upgrading from a basic toy to a cool robot!
