The Ādam Paradox Hypothesis 188
How This Supports APH’s Probability Ranges
70–85% under APH: Because these studies consistently show clusters of
fixed, human-specific regulatory changes in cognition genes, it is reasonable
to predict that genome-wide scans will confirm clustering around ~70kya.
<10% under Gradualism: Gradual models expect these changes to be
spread over 200k+ years. The probability of them aligning across DNA
mutations, epigenetic shifts, and TE/ERV insertions all near the same
window is vanishingly small.
2. Archaeological Predictions
Silence, Then Symphony.
Expect >200,000 years of anatomical modernity without enduring symbolic
artifacts, then a sudden burst around 70kya.
Mathematical Test:
If artifacts followed gradualism, frequency distribution across 300k years
should be uniform. Expectation: ~77% pre-70kya.
Observation: ~0% pre-100kya,
>90% after 70kya.
Likelihood Ratio (step vs. slope model):
Silence, Then Symphony — Made Simple
For more than 200,000 years, humans had modern bodies but left almost no
lasting art or symbols. Then, around 70,000 years ago, there was a sudden
explosion — cave art, beads, burials, carvings — all appearing almost at once.
If culture had evolved gradually, we would expect symbols to be spread out
more evenly across the last 300,000 years (about 77% of them should appear
before 70kya).
But what we actually see is the opposite:
Almost none before 100kya
Over 90% after 70kya
This is like silence followed by a sudden symphony. Statistically, the odds of this
happening by gradual chance are extremely low. When compared, the “step-
change” model of APH is more than 100 times better supported than the
gradual slope model.
