Parental care is expected to be one of the key evolutionary precursors to advanced social behavior. This suggests that there could be common genetic underpinnings to both parental care and sociality. However, little is known of the genetics underlying care. Here, we suggest that ethological predictions of behavioral precursors to care along with a genetic toolkit for behavior provide testable hypotheses and a defined approach to investigating genetics of sociality. We call this the 'precursor hypothesis'.
亲代照顾预计是高级社会行为的关键进化前体之一。这表明亲代照顾和社会性可能具有共同的遗传基础。然而,关于照顾的遗传基础知之甚少。在这里,我们提出行为预测的行为前体以及行为的遗传工具包提供了可测试的假设和定义的方法来研究社会性的遗传学。我们称之为“前体假设”。
