How are memories passed from one generation to another?

Trees are popular habitation environments for spiders.


Cellular Tissue of Instinct?

Years ago I used to watch insects while living in the Sierra Nevada Mountains. I did the same while living in the outskirts of Bangkok. One type of insect behavior that really caught my attention were infant spiders cutting open their egg sacks, emerging from their nests, and beginning to build their own spider webs.  There no other spiders around to show these newly emerged spiders how to build their own nests.  How did they possess the knowledge to do this?

There were no other spiders around to show them what to do that and no examples of other spider webs visible. I got to thinking. How does a spider with no education spin a perfect web? Without any instruction or examples to go by.

Incredible, I thought. And, a web which is identical to those of older spiders that I have seen before.
It was then that I began to question the idea of the possibility of memories being carried in the synapses of the brain instead of the spider's activity of web spinning explained away as instinct.

How many other insects and animals have this same attribute, that of executing a new behaviour almost immediately after birth without the benefit of example, or mother or fatherly instruction?

How many other insects, how many animals possess this trait, this ability, of being able to do a behavior without any formal training, no instruction, no living thing nearby to show, to instruct them in complex behaviors.  Behaviors such as spinning a web! 

So, I leave the reader with this simple thought. Are these unlearned behaviors an example of instinct or some message that is carried in the genes and chromosomes of these insects and animals?
