概括

蜜蜂失去了发育间隔,可能导致它们的成年寿命更长,这是社会行为的进化的一个关键因素. 基因组分析揭示了调节寿命的基因的变化,支持了这种进化联系.

科学领域:

进化生物学是进化的生物学.
基因组学就是基因组学.
昆虫的行为昆虫的行为

背景情况:

假设Diapause可以影响Hymenoptera中eusociality的演变.
尿路间隔时间的变化先于黄蜂和蜜蜂的社会进化,但基因组的基础尚不清楚.

研究的目的:

为了研究生命延长的基因组基础,在丧失了prepupal diapause之后.
为了测试这种假设,失去了隔离导致延长成人的寿命,这是eusociality的先决条件.

主要方法:

对27种蜂类的基因组比较分析,有和没有prepupal diapause.
检查IIS/TOR通路内的基因上的选择压力.

主要成果:

缺乏prepupal diapause的物种显示出延长寿命的潜在机制,包括PTTH及其受体的损失.
在调节寿命的基因中观察到趋同选择.
在IIS/TOR通路内确定了长寿基因的净化选择和抗长寿基因的放松选择.

结论:

在IIS/TOR途径上的选择压力的变化可能会延长寿命和改变营养反应.
这些适应对蜜蜂中eusociality的进化至关重要.

Convergent Evolution

Convergent Evolution

Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

Inclusive Fitness

Inclusive Fitness

Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.
