Are you afraid of spiders? This news is about old spiders. These spiders lived 410 million years ago.
Scientists study their fossils. They know how the spiders moved. They know the spiders’ bodies. They use this information. A computer programme makes a video. It shows how the spiders walked.
These old spiders ate insects. Today’s spiders are the old spiders’ “children”.
Difficult words: -ed (changes the verb to the past), fossil (when an animal changes into a thing like a rock), ate (past of “eat”).
