And this is the problem. Believers can't see anomalies, contrary argument, or any evidence that doesn't agree with their thinking.
You’re projecting. That’s actually “you”.
The thing is, your “contrary argument”, is not based on evidence, on logic or on reality.
Your “contrary argument” is merely deluded fantasies, believing that each individual organisms can consciously choose to “suddenly” evolve in any ways they preferred.
What of plants, fungi, archaea or bacteria? Are any of their species “conscious”?
With Evolution, biologists do accept and understand some populations of species can evolve, that the rates of adaption or rates of speciation can varied, some faster and some slower, but that’s all.
In the world of Bacteria (domain), they have shorter lifespan than most other life forms, eg eukaryotes like animals, plants & fungi, so bacteria reproduce in short time after they exist, asexually through cell division known as binary fission.
Depending on the species, the rate of when they start reproducing, can vary from within 10 minutes old (in the lab, it was observed that bacteria was 9.8 minutes old when it started cell division) to when they are day old or two. The parent bacteria would be gone, after successful production of two daughter bacteria.
If we go by the record of 9.8 minutes, then in a single day, a single individual parent bacteria, could have as many 147 generations, which would give a population of 1.78x10^44.
So let's say (hypothetically) you give antibiotic to kill the bacteria of 4th generation, population of 16 individual bacteria, of which only 1 individual is tolerant to the antibiotic, while the rest died. The surviving individual bacteria become a new parent.
And let's say in 90 days (3 months), that would be about 550 generations, and within those 3 months, month 1 for example, quarter die without reproducing, and month 2 about one-fifth died without reproducing, but on the 90th day, the new subspecies have become immune to that particular antibiotic.
90 days may not be long in human term, but I wouldn't call 551 generations to be "sudden". My calculator cannot even give me an estimate of the population in 551st generation.
For eukaryotic organisms, like humans, generations come in years and decades, so speciation take even longer between the Homo erectus and Homo sapiens. The Homo erectus (or the Homo heidelbergensis) didn't become suddenly Homo sapiens.
And the Homo sapiens cannot just wake up one morning and decide "I don't want to be Homo heidelbergensis any more". Conscious don't direct evolution.
Your notion that consciousness can control what we evolve into, would only exist in pseudoscience sci-fi novels or films, or in comic books.
Edit: My Windows calculator was about to calculate the 551st generation to be population of 7.3 x 10^165!!!! My guess is that my normal calculator cannot handle number of very long integer.
