I don't think you can make the assumption of deistic creation simply from an absence of evolutionary theory. The story provided by evolution is pseudo-theology which provides the modern world with part of its mythology. Biological science frankly melts much more often than that in other fields, whereas the evolutionary theory has been held fixed since the 19th century for basically ideological reasons, some of which supported most of the 20th century's killing.
So if we don't have evolutionary theory, then what? Well, we're discovering an entire field of Lamarckian epigenetics these days, though we're not allowed to call it that, because Darwin was right is a canonical received gospel of "science". That goes away, and we can start to conduct serious work into heredity. But more seriously, we start to return to a holistic view of the world, a premodern conception, in which an ecosystem is greater than the sum of its parts. Species certainly are recognized to adapt, but the mediating force is held at a respectful remove from our interaction with them, which is the critically important thing, and we can start respecting nature as a holy thing, rather than debasing both it and ourselves as creatures of the "sexual selection".
To go back to the real point, a bit beyond this thought exercise, of course species change and adapt according to the environmental conditions they find themselves in. So do humans, and indeed, so do human cultures. But the picture of this is far more complex than simple Darwinian evolution as still propounded by individuals like Dawkins et. al. and the picture that comes from strictly Darwinian evolution is a bleak, pitiless picture which has been used to justify racial holocaust and sexist subjugation of womankind alike, while slowing down biological-technical research and preventing us from maintaining a society capable of helping individuals, by denying the influence and importance of epigenetic heredity.
But doing that would run counter to the orthodoxy of established science, so we are left with these ferocious science-defenders, most being second-rate "scientists" themselves, policing the diversity of scientific endeavour.
Theories that incorporate ideas which negatively impact society are not worth having even if they are statistically more likely. Evolution refers to a set of events, and while those events are biologically important, they have been put into a framework which has had evil consequences for societies of the world in general. It would be better to disassociate the biological from the evolutionary framework and instead place it firmly into an ecological one, which is essentially congruous with conceptions of virtue and harmony across all cultures.
