合作的社会行为，如父母的照顾，长期以来一直被假设为放松选择，导致种群遗传变异的积累。虽然这个想法已经讨论了几十年，但研究社会行为如何影响群体遗传变异的实验工作相对较少。在这里，我们调查父母的照顾可以塑造亚社会昆虫，Nicrophorus vespilloides的分子遗传变异。使用全基因组测序的人口，在父母照顾的存在或不存在的30代，我们表明，父母的照顾保持水平的常设遗传变异。相比之下，在恶劣的环境下，没有照顾，强定向选择造成的遗传变异减少。此外，我们发现，适应护理的损失与种群之间的遗传分化有关的基因座压力，形态发育和转录调控。这些数据揭示了社会行为如何与塑造和维持种群遗传多样性的遗传过程联系在一起，并为一个古老的假设提供了罕见的经验证据。
Cooperative social behaviors, such as parental care, have long been hypothesized to relax selection leading to the accumulation of genetic variation in populations. Although the idea has been discussed for decades, there has been relatively little experimental work to investigate how social behavior contributes to genetic variation in populations. Here, we investigate how parental care can shape molecular genetic variation in the subsocial insect, Nicrophorus vespilloides. Using whole-genome sequencing of populations that had evolved in the presence or absence of parental care for 30 generations, we show that parental care maintains levels of standing genetic variation. In contrast, under a harsh environment without care, strong directional selection caused a reduction in genetic variation. Furthermore, we show that adaptation to the loss of care is associated with genetic divergence between populations at loci related to stress, morphological development, and transcriptional regulation. These data reveal how social behavior is linked to the genetic processes that shape and maintain genetic diversity within populations, and provides rare empirical evidence for an old hypothesis.
