Nature is never in a hurry, but always has time.

Finally, since they are the product of evolution, properties belonging to the nomological notion of human nature are not fixed, but they can change over time.[94]

Examples of properties that count as parts of human nature on the nomological definition include: being bipedal, having the capacity to speak, having a tendency towards biparental investment in children, having fear reactions to unexpected noises.

Therefore, human nature in the nomological sense does not define what it is to be a member of the species Homo sapiens.

Importantly, properties can count as part of human nature in the nomological sense even if they are not universal among humans and not unique to humans. In other words, nomological properties need not be necessary nor sufficient for being human. Instead, it is enough that these properties are shared by most humans, as a result of the evolution of their species – they "need to be typical".

It must be possible to explain the trait as the product of evolutionary processes. I

Machery clarifies that, to count as being "a result of evolution", a property must have an ultimate explanation in Ernst Mayr's sense.
