Hamilton's rule
E634418
Hamilton's rule is a principle in evolutionary biology that explains how altruistic behavior can evolve when the genetic benefits to related individuals, weighted by relatedness, exceed the costs to the actor.

How this entity was disambiguated
This entity first appeared as the object of triple T6995367 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.
Target entity: Hamilton's rule Context triple: [William D. Hamilton, knownFor, Hamilton's rule]
-
A.
Tinbergen rule
The Tinbergen rule is an economic principle stating that achieving a set of independent policy targets requires at least an equal number of independent policy instruments.
-
B.
Fisher's fundamental theorem of natural selection
Fisher's fundamental theorem of natural selection is a key principle in evolutionary biology stating that the rate of increase in fitness of a population is proportional to its genetic variance in fitness.
-
C.
Haldane’s rule
Haldane’s rule is a principle in evolutionary biology stating that when in the offspring of two different animal species or subspecies one sex is absent, rare, or sterile, that sex is usually the heterogametic one (e.g., XY or ZW).
-
D.
Hardy–Weinberg principle
The Hardy–Weinberg principle is a fundamental concept in population genetics that describes how allele and genotype frequencies remain constant from generation to generation in an idealized, non-evolving population.
-
E.
Hairston–Smith–Slobodkin hypothesis
The Hairston–Smith–Slobodkin hypothesis is an influential ecological theory proposing that predators keep herbivore populations in check, allowing plant biomass to flourish and helping explain why the world is "green."
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Subject: Hamilton's rule Description of subject: Hamilton's rule is a principle in evolutionary biology that explains how altruistic behavior can evolve when the genetic benefits to related individuals, weighted by relatedness, exceed the costs to the actor.
