Detecting design or intent in nature

[Heywood]

A system is an evolutionary system if it contains the following elements: Replication, Heritable traits, Change, and Selection. Some people did not like defining "evolutionary system" this way....so I said fine, lets call such systems "Heywood Systems". The labels don't change the argument.

There is a set of systems which contain those elements. Every time we examine members of that set and find them to require intellect without ever finding a member which does not require intellect, it increases the likelihood that all members of that set of systems require intellect.

So you made up the definition and made up that it requires intellect?

Negative Mr Wizard.

I made up the definition and then observed that no such systems(which contain the elements of replication, heritable traits, change, and selection) has ever been observed coming into existence without intellect. I further observed that when ever we could observe such a system coming into existence it always required an intellect. I then concluded from my observations that it is likely that all such systems require intellect to come into existence.

If my conclusion is wrong, it should be easy to show it is wrong by presenting an example of such a system which is known not to have required intellect. Please present an observation which falsifies my argument.
