I have written many times earlier about two types of people. Those with the Zoom-In mind and those with the Zoom-Out mind.

The Zoom-In mind is which zooms into things. Details, separating, differentiating, categorizing, specializing, splitting apart and so on. This is the mind  of the average scientist. Always seeing differences.....rarely integrating.

The Zoom-out mind is that which zooms out like a TV camera. Its puts together things that seem different. It integrates, finds similarities, sees everything as parts of a whole.  This is the mind of a philosopher. Always looking for the Big Picture.

Most people here (needless to say) are of the Zoom-In variety. All science enthusiasts,  but by their very nature and nurture only zoom-in people. They will never be able to integrate ideas and  put together seemingly disparate  phenomena.

As far as evidence for direction to evolution is concerned. Its everywhere....most people of the zoom-out variety will be able to see it at once. Those of the zoom-in variety sadly, will not be able to put them together.....that is all.  It is unfortunate but true.   

1. The very fact that such complexity has arisen with all the millions of emergent properties necessary....is enough evidence for a direction. Such complexity arising out of random processes...is ridiculous!

2. The Survival instinct and procreation instincts  born from DNA replication is another evidence of a goal.

3. Epigenetics/neo-Lamarckism are probably the mechanism (besides other unknowns) by which information gathered during ones life time are passed on to the progeny facilitating active adaptation. No need for random stuff.

4. Many other well known ideas such as the Copenhagen Interpretation of QM, Anthropic Principle, Gaia hypothesis all point to an active participation of Consciousness in the world....and to the world being a living system with constant feed back and regulation.

All this is enough evidence for a direction to evolution, according to me....certainly much more than is available for Dark Matter and Dark Energy......but I know that with the Zoom-In mindset of most people here none of this will make any sense. They will be back to baring their fangs with their crass and scornful remarks.    Unfortunate!
