If you're talking about pattern recognition of objects (say, identifying cave paintings or rocks used as spear tips), then that's not quite applicable to biology in the fashion you appear to be suggesting. Identification of designed artifacts is based on understanding of processes related to the formation of different observed patterns and the contrast of human-manufactured objects versus naturally occurring formations.
With biology you don't really have that same comparison since biological forms themselves are natural (as they occur in nature) since we don't have an alternative known source of origin. And the patterns we do observe already fit an evolutionary explanation.
To claim that natural things are not designed because they are natural is a bit circular and begs the question.
Given that a level of functional coherence is evident in natural forms that makes the very highest level of human designed functionally coherent systems look like Duplo bricks, an inference to design is obvious.
Metaphysical reasons for origins appears beyond the scope of what is being asked here.
So you say, but you are not the person asking the question.
An answer that fails to address the full scope of what is being asked in the name of limiting enquiry is a very poor answer at best.
If Science is unable to address issues beyond the natural scope then Scientists speaking professionally should refrain from any comment that refers to things that they know nothing about.
Biologists commonly recognise design in biology, for them that should be the end of it. That they feel that they have to deny reveals a metaphysical commitment to atheism that has nothing what so ever to do with the field of Science.
On top of that, you don't actually have a metaphysical explanation for the question at hand. So who cares?
Aknowledging the Creator is always part of a complete explanation.
And after all Evolutionists never ever fail to aknowledge the supposed role of evolution in an explanation even when evolutionary theory is wholly irrelevant to the topic being discussed.
Are you talking about probability arguments? Because there is a gaping problem with probability arguments when it comes to biology and trying to identify design that way. Namely constructing a probability based on all possible variables (which are unknown) and identifying the probability space of all viable outcomes (also unknown). Generally such probability calculation attempts tend to be highly limited in scope and therefore not particularly meaningful.
Douglas Axe does a very good job of describing the method in his book Undeniable How Biology Confirms Our Intuition That Life is Designed.
The vastly increased complications and integration exhibited by living things mean that levels of functional coherence evident are much, much higher than anything designed by mere humanity.
To recognise design where it is evident will only lead to far greater leaps and bounds of beneficial technological development in the world.
