parental investment includes any investment that increases offspring survival at the cost of the parent’s ability to invest in other offspring ⓘ the sex investing less in offspring tends to compete more intensely for access to mates ⓘ the sex investing more in offspring tends to be more selective in mate choice ⓘ |

Instruction
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.
