In light of the increasingly widespread adoption of these methods to understand the historical context of evolution, we commissioned several articles under the research topic “Dating the Tree of Life.” These papers explore current perspectives and future prospects for the integration of morphological and molecular data for extinct and extant taxa in the context of a unified, dated phylogeny for the biodiversity of Earth.
Laurin summarized recent developments and areas for future research in dating methodologies for producing timetrees.
Sharma and Giribet present an integrated fossil and molecular analysis of Opilione phylogeny, using sophisticated new tip-dating methods (Pyron, 2011) to incorporate paleontological data into molecular divergence-time estimation.
They find strong support for diversification of Opiliones beginning in the Ordovician-Devonian periods.
Their results provide an important early window on the functional evolution of molecular structure and protein function that drove the early history of life.
van Tuinen and Torres offer a cautionary perspective on the influence of uncertainty in estimated timetrees.
“By having a better understanding of online dating behavior and preferences, we can be better prepared to help ethnic groups, including Hispanics, find the type of partner they’ll like.” The study, which surveyed Zoosk members across the country via web, also unveiled the following trends about Hispanics: A majority of Hispanic respondents kiss friends and family on the cheek, but when it comes to dating and kissing, they tend to be more reserved – 80% of female respondents kiss family and friends on the cheek, but nearly 30% of them think a date might get the wrong idea if they kiss the date on the cheek – Nearly 54% of female and 51% of male respondents say they wait until at least after two to three dates to exchange a first kiss Even though Hispanic families are supportive of couples moving in, respondents may still be cautious – 60% of female respondents and 69% of male participants said their families would be supportive of them moving in with their partner before marriage – Nearly 70% of female and 60% of male respondents said they had never moved in with someone they have dated – When considering moving in together, 24% of female respondents said they would wait until after getting married.With the #1 grossing dating app and a top 25 grossing app on the i Phone in the United States in 2014, Zoosk is a market leader in mobile dating.Available in over 80 countries and translated into 25 languages, Zoosk is a global online dating platform.The Tree of Life has an inherently temporal component, which was often overlooked in the early history of systematics.Every branch in a phylogeny has a specific beginning and end in time, and every node has an age.
