What is Campfire and its features?
Campfire is an online tool suite for world building projects, offering modules like species, languages, religions, and magic systems, along with narrative tools such as character sheets, timelines, maps, and relationship webs. Users can access Campfire for free, with the option to unlock extra features through a one-time purchase or a subscription starting at 50 cents a month. Projects created on Campfire are securely stored in the cloud, with the choice to keep work private or share it on the Explore tab to engage with a community of users and build an audience.
How do mutualistic relationships evolve?
Mutualistic relationships evolve when benefits to both species outweigh costs, leading to instances like the relationship between chemotrophs and algal symbiotes, and chromatophytes and pycopterans. These relationships may evolve due to changing climates, like the erosion of mountains allowing rainforest species to spread inland, leading to the need for cooperation for survival.
What is the significance of sociality in species?
Sociality evolves in species like phylactocanthids and hoplopods for mutual protection from predators, with the development of sentinel behavior and reciprocal altruism to ensure group survival. This provides competitive advantages, increased protection, hunting success, and easier access to reproduction for species like enzodonts.
How does cooperative hunting benefit species?
Cooperative hunting between different species, like groupers and moire eels, enhances hunting efficiency. Specialized pack hunting species evolve permanent associations and division of labor during hunts, like lionesses encircling prey and chimpanzees dividing hunting roles, leading to increased success in taking down prey.
What is the role of parental care in species?
Species with slow growth rates or high resource requirements benefit most from parental care. Female parental care is common due to higher reproductive investment, while male-only care is rare. Biparental care often accompanies monogamy, allowing males to invest in offspring care, with bird species commonly exhibiting this behavior due to highly altricial young.

- Cooperation among organisms, despite the evolutionary favoring of selfishness, is common in nature, with mutualistic symbiosis being a prevalent example where both species benefit.
- Mutualism is selected for when benefits to both species outweigh costs, leading to various instances like the relationship between chemotrophs and algal symbiotes, and chromatophytes and pycopterans.
- Mutualistic relationships may evolve due to changing climates, like the erosion of mountains allowing rainforest species to spread inland, leading to the need for cooperation for survival.
- Phoresis, a form of commensalism, is utilized by species like pronocanthids to disperse across landscapes, with benefits like feeding on parasites and providing defense to hosts.
- Sociality evolves in species like phylactocanthids and hoplopods for mutual protection from predators, with the development of sentinel behavior and reciprocal altruism to ensure group survival.
- Pack hunting, a behavior seen in various species for taking down large prey, is beneficial but not evolutionarily stable in most cases, with its rarity in rainforests attributed to abundant prey availability.

"Pack Hunting Dynamics in Tropical Ecosystems"
- Tropical plains of the western continent house titanopods, too large for apex predators like incidents to hunt alone, leading to pack formation based on ecological factors.
- Optimal pack size for incidents is 4 to 10 members, balancing prey takedown efficiency and resource distribution.
- Pack hunting species exhibit fluctuating group sizes based on prey availability, with foosa occasionally grouping for hunts.
- Specialized pack hunting species evolve permanent associations and division of labor during hunts, like lionesses encircling prey and chimpanzees dividing hunting roles.
- Cooperative hunting between different species, like groupers and moire eels, enhances hunting efficiency.
- Enzodonts establish hunting roles based on age, size, and experience, with younger members blocking prey escape while older members make the kill.
- Sociality provides enzodonts competitive advantages, increased protection, hunting success, and easier access to reproduction.
- Lekking behavior, gathering males in one spot during breeding season, streamlines mate selection and drives male competition and sexual dimorphism.
- Vocalizations in lekking species evolve for mate attraction, with sound signaling in dense vegetation environments.
- Camara brackets rely on vocalizations for social coordination, forming lex of up to 100 males, exhibiting polygeny and male competition in haremic mating systems.

Parental Care in Species with Slow Growth
- Species with slow growth rates or high resource requirements benefit most from parental care.
- Female parental care is common due to higher reproductive investment, while male-only care is rare.
- Biparental care can occur if ecological factors increase male reproductive costs.
- Biparental care often accompanies monogamy, allowing males to invest in offspring care.
- Bird species commonly exhibit biparental care due to highly altricial young.
- Inclusive fitness explains altruism, with relatedness influencing altruistic behaviors.
- Hamilton's rule predicts altruistic behaviors based on relatedness and costs.
- Cooperative breeding, like helpers at the nest, enhances inclusive fitness.
- Monogamy maximizes relatedness, crucial for cooperative breeding success.
- Reproductive suppression occurs in social groups with high relatedness and altricial young.

Colonial organisms exhibit complex social organization.
- Colonies of animals, such as eryktochyrids, reproduce through dispersal of male and female individuals to form new colonies, exhibiting complex social organization.
- Colonial organisms, like genets or zouans, consist of interdependent organisms called remits or zooids, with specialized morphs fulfilling specific functions within the colony.
- Colonial plants, known as zygophytes, evolve division of labor and differentiation into specialized structures, benefiting from mutualism with pollinators and seed dispersers in tropical areas.
- Multicellular organisms, including colonial organisms, exemplify sociality through interdependent cells with differentiated functions, with only sex cells involved in reproduction and passing on shared genes.
