Are spiders older than insects?
Not surprisingly, insects evolved from sea-dwelling crustaceans. What is surprising is that a group of arthropods known as “Chelicerata,” which includes spiders, scorpions, ticks, and mites, branched off from early crustaceans before insects did, making spiders older than insects.

When did insects and spiders first appear?
Fossil evidence suggests that the first insects lived about 412 million years ago, during the Early Devonian Period. But the researchers’ phylogenetic data indicates that the largest group of insects, hexapoda, may have evolved even earlier, around 479 million years ago, during the Early Ordovician Period.
When did spiders first appear in the wild?
Emergence of true spiders. Spiders with spinnerets at the end of the abdomen ( Mygalomorphae and Araneomorphae) appeared more than 250 million years ago, presumably promoting the development of more elaborate sheet and maze webs for prey capture both on ground and foliage, as well as the development of the safety dragline.

Why are spiders considered to be a creation?
Spiders are a sophisticated creation. There are a number of spider kinds that surf the sky as babies. These kinds of spiders will spin a thin strand of web and leap into the wind where they can sometimes be carried thousands of feet into the air and for hundreds of miles. They are able to hang on to their threads and ride them like air surfboards.
