Limits RegistryPUBLIC RECORD
Limits RegistryThe African elephant (Loxodonta africana) has around 2,000 functional olfactory receptor genes, roughly five times more than humans (about 400) and more than any other mammal genome sequenced to date, consistent with its exceptionally acute sense of smell used for foraging, water detection, and social communication.
The question, scope, and sources behind this Registry record.
The African elephant (Loxodonta africana) has around 2,000 functional olfactory receptor genes, roughly five times more than humans (about 400) and more than any other mammal genome sequenced to date, consistent with its exceptionally acute sense of smell used for foraging, water detection, and social communication.
The largest number of functional olfactory receptor genes identified in the genome of any sequenced mammal species, as reported in comparative genomics literature.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
