首项研究中,英国东安格利亚大学学者安德斯·伯格斯特龙与克里克研究所庞图斯·斯科格伦德带领团队,对来自欧洲及周边区域的216具犬狼遗骸进行了基因测序。年代最久远的样本出自瑞士考古点,经碳十四测定距今1.42万年。基因比对显示,该犬种与其他地域犬类拥有共同祖先,证明家犬的遗传分化在1.42万年前就已开始,且欧洲旧石器时代的犬类并非独立驯化的产物。
Concise APL code is also very useful when trying to get help for proper solutions. Having snippets, like the example, containing few intermediary variables, focusing on data transformations and being written in a few lines allows me to cut segments from my pipelines and present them to people for possible optimizations. Most of the time, they don't even need to know how these segments fit into the broader picture of what I'm doing (Usually just need to specify what data the segments work on and what I expect out of them). The difference between sharing a few lines of code and being able to bounce around possible solutions versus 40 lines that do the equivalent thing is huge, especially when doing it in a chatroom.
