Spider webs are awesome examples of the ability to construct unbelievably strong structures! I love to photograph them and am in awe of this marvel of nature.

Thought not as strong as steel, the webs are very strong. Consider this information from Wikipedia - "Spider silk is a protein fibre spun by spiders. Spiders use their silk to make webs or other structures, which function as sticky nets to catch other animals, or as nests or cocoons to protect their offspring, or to wrap up prey. They can also use their silk to suspend themselves, to float through the air, or to glide away from predators. Most spiders vary the thickness and stickiness of their silk for different uses."

How did the spider get the wisdom and ability to do this? Food for thought! Intelligence cannot just happen.
