Place / region: Jebel Irhoud; Morocco; North Africa

What this establishes

Layer 7 thermoluminescence estimate: 315 ± 34 ka at 1σ.

The morphology paper describes a mosaic of modern-looking and more primitive features.

What it does not establish

The dated material is associated heated flint; the estimate is not a direct calendar date for every fossil.

These finds do not identify the first Homo sapiens or establish one geographic origin for the species.

Fresh inspection of the specified supporting passages for this revision. Scope and access vary by source; no comprehensive literature or raw-data audit is implied.

Age convention: The paper reports thousand years ago (ka); no conversion to an exact BCE calendar year is made. The inspected age passages do not establish a radiocarbon-style 1950 BP baseline. Publication year may be used only as a disclosed navigation convention, not a measurement baseline. The publication year 2017 anchors ordering only. Estimate: 315,000 ± 34,000 years. 1σ, as reported for layer 7 thermoluminescence. Navigation envelope: 247,000–383,000 years; nominal 95% interval reported by the paper.

Date note: The main date represents the estimated age of the associated layer, not a discovery date or the origin of the species. Layer 7 heated flints supply the 315 ± 34 ka estimate; the accompanying morphology study appeared in 2017.

What this establishes

The inspected Figure 1 labels M1 as 73 ± 3 ka using OSL dates.

The authors identify deliberately applied ochre lines on ground silcrete.

What it does not establish

Context dating estimates the archaeological phase, not the exact moment of drawing.

The pattern does not establish language, a particular belief, or a decipherable symbolic message.

What this establishes

The 2017 study modelled the earliest occupation onset at 65.0 ± 5.7 thousand years, including systematic error.

Research took place with permission from the Gundjeihmi Aboriginal Corporation.

What it does not establish

The estimate depends on sediment dating and archaeological context; no exact first landing or unchanged culture across 65,000 years is established.

What this establishes

Archaeological and genetic syntheses support multiple independent centers and processes lasting centuries or millennia.

Cultivation can precede the biological traits used to identify domestication.

What it does not establish

Regional chronologies differ. Farming, herding, gathering and hunting often coexisted; the broad range does not describe every community.

Historical strand: Food, work & exchange · Cultural traditions & expression

Place / region: Mali and the Sahel; Cairo; Mecca; West Africa, North Africa and Arabia

Culture / tradition: Medieval Malian and Sahelian political, commercial and scholarly traditions

What this establishes

The Met dates the journey to 1324–25 and documents its wider visibility.

Its Sahel synthesis distinguishes long-standing local urban development from later external connections.

What it does not establish

This journey illuminates wider systems; it did not create West African urban life or all of Timbuktu’s scholarship. Claims of a calculable modern-dollar personal fortune are not used.

Historical strand: Health & public welfare · Food, work & exchange

Place / region: Western Europe and England as the defined episode; context within a wider Afro-Eurasian pandemic

Culture / tradition: Medieval communities and labor systems

What this establishes

Population recovery was suppressed by later outbreaks.

English labor regulation responded to shortages and rising wages.

What it does not establish

Mortality estimates and regional experiences differ. A Cambridge study found no dramatic health or lifestyle changes directly attributable to the epidemic in its skeletal evidence.

What this establishes

The Library of Congress dates production in Mainz to 1454–1455.

Printed copies were subsequently finished by hand and differ in their decoration and binding.

What this establishes

American crops became important foods in Africa, Asia and Europe.

Caribbean colonization combined disease, forced work and disrupted agriculture.

What it does not establish

Columbus did not discover an uninhabited continent. One voyage did not alone cause every later transformation; outcomes varied and population-loss estimates remain uncertain.

The 1543 Nuremberg printing was produced by Petreius after Rheticus helped bring the manuscript to publication.

What this establishes

Part II states four precepts governing inquiry and review.

What it does not establish

This publication did not originate all systematic reasoning or experimental practice.

Descartes's wider metaphysical arguments are not treated as experimentally established findings.

What this establishes

What it does not establish

Later additions, including the General Scholium, must not be dated to the 1687 first edition.

What this establishes

Cotton manufacturing moved toward large, mechanized factories.

Manchester’s cotton industry relied heavily on raw cotton produced by enslaved people in the United States.

What it does not establish

This Britain-centered anchor does not date every society’s industrialization.

Industrial growth involved unequal benefits, coercion and environmental harm; it was not uninterrupted progress.

WHO describes vaccination, surveillance and containment as central to eradication declared in 1980.

What it does not establish

Earlier variolation in Asia, Africa and the Ottoman Empire, and local cowpox knowledge, preceded Jenner.

What this establishes

The Library of Congress dates the declaration to January 1, 1804.

Its scholarly guide describes the revolution’s influence on US abolitionist and proslavery politics.

What it does not establish

Independence did not produce immediate international recognition: the United States withheld recognition until 1862.

The revolution and its aftermath included violence and political conflicts; freedom was not a simple endpoint.

What this establishes

The journal issue is dated May 1, 1888 and the report explicitly credits Golgi’s methods.

On p. 5 Cajal says the described fibers do not join each other and apparently terminate freely.

What it does not establish

The cautious language should be preserved; this paper did not directly image synaptic gaps or establish all mechanisms of neural communication.

A finished neuron doctrine should not be dated wholesale to this single preliminary report.

What this establishes

Chapter IX identifies five features of thought, including personal ownership, change, continuity and selection.

James frames the chapter as the beginning of studying the mind from within.

This is a historical theoretical and introspective account, not proof of a complete mechanism of consciousness.

No inference about paranormal agency, non-human intelligence or quantum consciousness follows from the chapter.

What it does not establish

The sample still contained much barium; this paper did not report isolated pure radium metal.

Radioactivity is a physical phenomenon; the authors’ historical energy speculation should not be repeated as a modern conclusion.

What this establishes

The published paper reports Cepheids in M31 and M33 and applies Shapley’s period–luminosity calibration.

Carnegie dates the announcement to January 1925 and identifies Leavitt’s distance-marker contribution.

What it does not establish

The 1925 distance scale was preliminary and should not be presented as today’s accepted numerical distances.

This extragalactic-distance milestone is distinct from Hubble’s 1929 velocity–distance paper.

What this establishes

The 1927 text derives an approximate proportionality between apparent recession velocity and distance.

It uses Hubble’s magnitudes and Strömberg’s compilation of radial velocities to estimate the factor of proportionality.

What it does not establish
