2026: the year so far
This developing annual review compares the fossil, molecular, archaeological and experimental evidence checked so far. The methods add different kinds of evidence, and their results are not interchangeable.

01 · EDITORIAL ANALYSIS
Denisovans gain fossils and an ecological setting
- The finding
- Bianfu proteins identify two teeth and three bone fragments in approximately 167–134 ka layers; a companion study describes a wider archaeological sequence.
- What changed
- The molecularly confirmed record expands in southwestern China, alongside evidence of animal processing and forest-resource use.
- Possible consequences
- Comparisons can now ask how Denisovan populations used different environments and how protein evidence aligns with anatomy.
- Evidence limits
- The wider 190–70 ka sequence is not continuous occupation established by molecular evidence. Protein assignments are not complete genomes.

02 · EDITORIAL ANALYSIS
An adult fossil strengthens the early erectus case
- The finding
- DNH 127 adds adult cranial evidence tentatively assigned to Homo erectus sensu lato in the roughly 2.04–1.95 Ma Drimolen context.
- What changed
- An attribution previously supported by a juvenile gains an adult comparison. WAWL has corrected its older displayed range.
- Possible consequences
- The discovery helps researchers compare early Homo populations and the traits used to classify fragmentary remains.
- Evidence limits
- An early occurrence is not a demonstrated geographic origin, and species boundaries remain debated.
Sources: Martin et al.
03 · EDITORIAL ANALYSIS
Farming and landscape change were regional processes
- The finding
- Belize soils record changing cultivation locations; Lower Yangtze isotopes trace dietary shifts; Madagascar livestock spread coincided with vegetation changes.
- What changed
- These are separate local histories with different evidence, timescales and uncertainties.
- Possible consequences
- Comparative work can test how food production, settlement and environmental pressure interacted without assuming a universal sequence.
- Evidence limits
- Isotope signals are not always crop-specific. Association with livestock does not establish a single cause of extinction.

04 · EDITORIAL ANALYSIS
New methods change which questions can be asked
- The finding
- Cell experiments connect skeletal regulation to cartilage chemistry, while teaching experiments test how selected information survives between learners.
- What changed
- Mechanistic and experimental evidence joins the fossil and archaeological record.
- Possible consequences
- These methods can make hypotheses more precise and testable across disciplines.
- Evidence limits
- Modern cells and learning tasks do not reconstruct extinct individuals or date the origin of teaching.

05 · EDITORIAL ANALYSIS
Microbial histories add a new comparison
- The finding
- Contemporary Tsimane and Hadza microbiomes contain patterns consistent with prehistoric movements of their hosts.
- What changed
- The study adds microbial evolutionary histories to questions previously approached mainly through human genomes and material evidence.
- Possible consequences
- Concordance and disagreement among these records can help test migration models.
- Evidence limits
- These are present-day microbial samples and model-based historical inferences, not recovered prehistoric genomes or established health effects.
Sources: Carter et al.
Questions still open
- Broaden the annual selection across regions, methods and earlier months before year close.
- Distinguish a changed WAWL summary from a changed scientific consensus.
- Assess which findings survive independent comparison and correction.
