Spiders Defy Darwinian Expectations

Spiders keep on amazing us with their skills, Some can glide for over 20 metres, some gather water with their webs.

As David Attenborough puts it, we have yet to invent a material that would be as strong, light and elastic as spider’s silk.

Using their webs, spiderlings can climb hundreds of metres into the air, and with a little help from strong winds, practically fly for thousands of kilometres.

There’s more:

Bagheera kiplingi is a Central American spider that mostly eats vegetables.
Peacock spiders are astoundingly beautiful.

Spiders have remained practically unchanged for aeons. A ”49 million years” old specimen trapped in amber looks very much like today’s spiders, as does an older one dated at ”165 million years”.

They remind us of the wonders of creation as well as the consequences of the Fall.
