The evolution of spiders has been going on for at least 400 million years, since the first true spiders (thin-waisted arachnids) evolved from crab-like chelicerate ancestors. Today, there are 42,473 described spider species within the diverse phylum of arthropods.
Major developments in spider evolution include the development of spinnerets and silk secretion.
Among the oldest known land arthropods are Trigonotarbids, members of an extinct order of spider-like arachnids.
Trigonotarbids share many superficial characteristics with spiders, including a terrestrial lifestyle, respiration through book lungs, and walked on eight legs, with a pair of leg-like pedipalps near the mouth and mouth parts. Arguments still remain open as to whether they possessed the ability to create silk. This had been a popular thought for quite some time, until an unpublished fossil was described with distinct microtubercles on its hind legs, akin to those used by spiders to direct and manipulate their silk.

"You can only describe the tropical whip spider as evolution’s perfect design for an arthropod killing machine," says Verner Bingman, a behavioral neuroscientist and National Geographic grantee. While whip spiders are arachnids that fall under the arthropod phylum, they're not actually spiders. Whip spiders have eight legs, but the front two have evolved into antenniform legs that extend up to two feet long. These legs wiggle around like whips to gather sensory information, earning whip spiders their name. The arachnids also have appendages called pedipalps, which Bingman describes as being like "pliers with sharp teeth." "They're these kind-of serrated blades that the whip spiders use to clasp and crush its prey," he says. "They have remarkable weaponry for killing." Despite his chillin...

THE American house spider (Parasteatoda tepidariorum) produces a web with adhesion that can be strong enough to stick to a wall or weak enough to detach from the ground and thus act as a spring-loaded trap for walking prey. How does the spider produce both strong and weak anchors for its web with a single type of glue? A spider’s scaffolding disc Scaffolding silk Consider: The spider anchors its web to a wall, a ceiling, or a similar surface by weaving highly adhesive patches of silk called scaffolding discs, which are strong enough to withstand the impact of flying prey. Researchers at the University of Akron, Ohio, U.S.A., have discovered that, on the other hand, the patches of silk that are attached to the ground—called gumfoot discs—have an entirely different architecture, or constru...
