Did spiders evolve from crabs?

Just as we all humans have a common ancestor, these all arthropods have a common ancestor. They all evolved from one arthropod. So neither the crabs evolved from spiders, nor the spiders evolved from crabs. They are like cousins to each other.

Why are humans afraid of spiders?

There are other reasons and theories about why so many people are afraid of spiders. Some say it's a learned response through family or culture; however, it's possible that someone's brain chemistry may dispose them to arachnophobia. A bad experience with spiders can also lead to a lifelong fear.

Did spiders evolve from scorpions?

Analysis of these genomes revealed that spiders and scorpions evolved from a shared ancestor more than 400 million years ago, which made new copies of all of the genes in its genome, a process called whole genome duplication.
