On the cover: Medicine is the practice of the diagnosis, treatment, and prevention of disease. With the advances in medical science, human beings are getting both longer life spans and higher quality of life. From herbs to molecular signatures, humankind is experiencing a transition from traditional medicine to personalized medicine: the right treatment to the right patient at the right time. However, it is not so easy to achieve this goal because the etiology of most diseases and disorders is still unclear. From description to association, numerous researchers are working together to decipher the mechanisms behind disease. To address such challenges, more and more global collaborations are badly needed to include experts from all disciplines: not just doctors, scientists and administration staff, but also engineers, technicians and marketing managers. Not limited to a fish-eye view, we humans should widen our vision and get more deep insights beyond the human community. That is the right way to assure sustainable healthcare for humanity. |

Graphical abstract
Parallel evolution of reproductive isolation (PERI) provides strong evidence for natural selection playing a fundamental role in the origin of species. However, PERI has been rarely demonstrated for well established species drawn from different genera. In particular, parallel molecular signatures for the same genes in response to similar habitat divergence in such different lineages is lacking. Here, based on whole-genome sequencing data, we first explore the speciation process in two sister species of Carpinus (Betulaceae) in response to divergence for temperature and soil-iron concentration in habitats they occupy in northern and southwestern China, respectively.
