Sapien

A male Sapien in a coat.

Overview

A sapien is a human that lives in the game. These sapiens make up your tribe and do the work that the tribe needs. Sapiens possess unique physical characteristics, genetic traits, and skill sets determined at birth through a mix of inheritance and random generation.

Age

Each sapien has an age associated with it, representing its current stage of life. Sapiens live for a total of 70 days, though the in-game UI displays their age as 5 at birth and 75 at the end of their lifespan.

Baby

• Duration: 1 day.
• Status: Carried by the mother; the mother cannot perform skills requiring heavy lifting during this time.
• Gender: Determined by a random 50/50 roll at the moment of birth.

Child

• Duration: 10 days.
• Physical Limits: Cannot perform heavy lifting, carry babies, or become pregnant.
• Movement: 1.1x walk speed multiplier. Animation speed is 1.5x faster to account for smaller leg span.
• Eye Height: 0.9m (Standing) / 0.6m (Sitting).

Adult

• Duration: 50 days.
• Capabilities: Primary labor phase with a 1.5x walk speed multiplier.
• Reproduction: Females are fertile until they reach 70% of this stage (Day 46 of total life). There is a 4.1-day minimum cooldown between pregnancies.
• Eye Height: 1.5m (Standing) / 0.8m (Sitting).

Elderly

• Duration: 10 days.
• Physical Limits: Cannot perform heavy lifting or reproduce. Moves at base (1.0x) speed.
• Death: Occurs automatically once the 10-day duration is complete.
• Eye Height: 1.5m (Standing) / 0.8m (Sitting).

Reproduction and Inheritance

Pregnancy Requirements

A female adult may become pregnant if:

• Resources: The tribe has at least 5 food items.
• Population: The tribe is under the population cap.
• Social: High bond/mood with a male seen within the last 300 seconds.
• Loyalty: Above "mild negative" mood.

Inheritance Logic

• Skin Color: A 33.3% chance each for Mother's tone, Father's tone, or a linear 50/50 average.
• Genetics: Hair and eye color have a 50% chance to be inherited from the father; otherwise, they default to the mother.
• Social Status: Children inherit the mother’s Tribe ID, Nomad status, and current skill priorities (Roles).

Traits and Health

• Trait Generation: Sapiens are born with 1 to 3 random traits.
• Learning Speed: Traits like Clever/Slow modify the base learning rate exponentially. Clever sapiens learn ~1.41x faster, while Slow sapiens learn ~0.71x as fast.
• Immunity: The "Immune" trait doubles the base virus immunity duration (from 16 days to 32 days), while "Weak Immunity" halves it.
• Environment: Clothing (woolskins) and warm beds protect sapiens by shifting their effective temperature zone toward "Moderate."

Death

• Old Age: Sapiens die after 70 days of life (displayed as Age 75).
• Grieving: Death causes family and friends (bond > 0.5) to suffer a 0-happiness status effect.
• Hazards: Sapiens can die from starvation, hypothermia, or critical injuries (mammoth attacks or infected wounds).
