The Evolution Deceit Engineering in the Cobweb Have you ever
noticed the shapes of spider webs? Did you know that spiders
produce their thread themselves and that this thread has some
amazing characteristics? Or have you heard that the techniques
used by garden spiders to spin a web are the same as those used
by civil engineers today? A spider needs two separate places in
order to spin its web. Webs are generally spun in a corner where
two walls join or between two branches. However, some spiders
are so skilful that they spin their webs using a single surface.
How a spider spins its web is spectacular. Now try to visualize
what we will tell you here. A spider first finds a flexible
