i don't understand the concept.
its apparent that some evolution evolves to a greater form, while other forms of the same initial start appear to devolve.
the devolution leads to extinction, while the evolution leads to survival.
for instance: if we say ape's evolved upward to man, but evolved form the lesser initial, the lesser initial is the start of man. but if all evidence was to show man before apes in the fossil records, then it would be apparent that apes are a devolution of man.
in lack of any evidence, there can be no conclusion. but this is conclusive: that dogs "appear" to be a devolution of the wolf, since the wolf has a greater mind. the devolution of the aggressive properties leads to a less aggressive, less smart, yet more man friendly version of wolf: dog.
a evolution project on foxes discovered that quite quickly by selective breeding of an animals flight distance led to a friendly colorful fox ina very short period of time, much shorter than what initially was believed to be possible.
I'm not sure where there observation would be relative to teleological science tho. i fail to understand where a=b,c,d,f.
when more apparent is a=b AND B AND B AND B AND THEN B= C C C C C C and then c c c c c c= d d d d d d d d d d d d.
i hope i didn't overstep my abilities in my lack of understanding.
keep your mind from this way of enquiry, for never will you show that not-being is
