🧵 does evolution favor the species or the individual?

I was thinking about evolution after I sneezed earlier today.
Sneezing spreads pathogens much further than if one were to blow their nose into a tissue or their hand or whatever, so this makes me think that the mechanism of sneezing was evolutionarily chosen to favor the individual over the group.
But we can see many cases of evolution benefiting “the group”, especially in ants and honeybees.
I wonder if one focus of evolution is much more common than the other?

evolution favor genes. it doesn't give a shit about species or "individuals" (collection of genes)

it favors the individual cuz that's the vessel the genes are stuck in

no, family altruism disproves this
genes are spread between several vessels, the more related you are the more likely you share genes
genes favor altruism within familial units not the individual
reality is fundamentally communist

intelligence and intent are abstract emergent concepts of themselves

Evolution favors whatever organism has the most offspring

Multi-level selection, complicated even more in humans with the emergence of complex cultures

And copies of those genes exist in other vessels, so it’s beneficial for copies of the same genes to cooperate (a mother being nice to her baby for example)

Your observation about the potential conflict between individual and group interests in evolution is quite intriguing. Evolutionary theory considers both individual and group-level selection pressures, and the balance between them can vary depending on the species, environment, and specific traits being considered.
1. **Individual selection:** This focuses on the survival and reproduction of individual organisms. Traits that confer advantages to individual organisms, such as enhanced ability to obtain resources, avoid predators, or reproduce, are favored by natural selection. Examples of traits shaped by individual selection include adaptations for efficient locomotion, predator evasion, and reproduction.
2. **Group selection:** This emphasizes the survival and reproductive success of groups of organisms, such as families, social groups, or populations. Traits that enhance the overall fitness of the group, even if they come at a cost to individual fitness, may be favored by group selection. Examples of traits shaped by group selection include cooperative behaviors, altruism, and social structures that promote cooperation and division of labor.
The relative importance of individual and group selection can vary depending on factors such as the species' social structure, reproductive strategy, environmental conditions, and the specific traits under consideration. For example:
- In species with highly cooperative social structures, such as ants, bees, and certain species of birds and mammals, group-level selection may play a significant role in shaping traits related to cooperation, division of labor, and altruistic behavior.
- In species with more solitary or competitive lifestyles, individual selection may dominate, favoring traits that enhance individual fitness and reproductive success.
- In some cases, traits may be shaped by a combination of individual and group selection, with the balance between the two varying depending on the specific ecological contex
