Hey mate mark as brainliest. cause i need it.
Step-by-step explanation:
A cocoon is a silky web spun around the larvae of many insects. Caterpillars emerge from their cocoons as beautiful butterflies. The word cocoon can also refer to a form a self-protection for humans.
Our ancestors - and the spiders' ancestors - with different numbers of legs didn't live and reproduce. 8-legged spiders and 2-legged people survived and reproduced. Spiders have 8 legs, because their ancestors had 8 legs. Spiders and horseshoe crabs evolved from the same ancestors!
