Mystery of bottle gourd migration to Americas solved

The content is provided for information purposes only. For several decades, scientists have been wrangling with the mystery of how the bottle gourd, which is believed to be native to Africa and Asia, made its way to the Americas where it grew wild approximately 10,000 years prior to being domesticated. Some believed the mystery had been solved when a research team using DNA techniques reported back in 2005 that the bottle gourd in the Americas had Asian DNA, suggesting the gourd made its way to North America by early people carrying it across the land bridge that existed between what is now Alaska and Russia. In this new effort, the research team contradicts that earlier finding claiming that newer DNA analysis tools show that gourds in the Americas actually have African DNA, which suggests they made it to the New World by floating across the ocean.To settle the matter once and for all, the researchers analyzed 86,000 base pairs taken from samples, rather than the meager three markers used in the 2005 study. It proved, the team says, that the bottle gourd found its way to the Americas from Africa on its own, grew wild for a time and was then cultivated. To further bolster their claim, the team created a computer simulation of bottle gourds and the waters through which they would have had to travel. The simulation showed it was possible the gourds could have traveled to the ocean via African rivers or streams, then made their way across the ocean via currents to the coast of South America, all in just nine months—a short enough span to allow for the seeds contained within to grow once reaching land.The new research appears to settle the matter of how the bottle gourd got to the New World, but questions still remain, such as how it got to Asia, and why are there so few wild variants of the bottle gourd anywhere in the world today?

PNAS, www.pnas.org/cgi/doi/10.1073/pnas.1318678111AbstractBottle gourd (Lagenaria siceraria) was one of the first domesticated plants, and the only one with a global distribution during pre-Columbian times. Although native to Africa, bottle gourd was in use by humans in east Asia, possibly as early as 11,000 y ago (BP) and in the Americas by 10,000 BP. Despite its utilitarian importance to diverse human populations, it remains unresolved how the bottle gourd came to be so widely distributed, and in particular how and when it arrived in the New World. A previous study using ancient DNA concluded that Paleoindians transported already domesticated gourds to the Americas from Asia when colonizing the New World [Erickson et al. (2005) Proc Natl Acad Sci USA 102(51):18315–18320]. However, this scenario requires the propagation of tropical-adapted bottle gourds across the Arctic. Here, we isolate 86,000 base pairs of plastid DNA from a geographically broad sample of archaeological and living bottle gourds. In contrast to the earlier results, we find that all pre-Columbian bottle gourds are most closely related to African gourds, not Asian gourds. Ocean-current drift modeling shows that wild African gourds could have simply floated across the Atlantic during the Late Pleistocene. Once they arrived in the New World, naturalized gourd populations likely became established in the Neotropics via dispersal by megafaunal mammals. These wild populations were domesticated in several distinct New World locales, most likely near established centers of food crop domestication.center_img Explore further (Phys.org) —A team with members from several institutions in the U.S. has finally set to rest the mystery of how the bottle gourd found its way to the Americas. In their paper published in Proceedings of the National Academy of Sciences, the team explains that new DNA analysis has revealed that the bottle gourd made its way to South America by floating over from Africa.

Tableau Day highlights Augmented Analytics Tableau Prep Builder and Conductor and more

first_imgThe Tableau community held a Tableau Day in Mumbai, India, yesterday. The community announced some upcoming and exciting developments in Tableau. Some of the highlights of the Tableau Day include an in-depth explanation of the new Tableau Prep Builder and Conductor, how Tableau plans to move on to Augmented Analytics, and many others. The conference also included a customer story from Nishtha Sharma, Manager at Times Internet, who shared how Tableau helped Times Internet in optimizing their sales, revenue, managing cost per customer, and business predictions with the help of Tableau Dashboards. She further said, Times Internet was solving around 10 business problems with 7 dashboards initially; however, due to success with Tableau initially, they are now solving close to 30 business cases with 15 dashboards. Let us have a look at some of the highlights below. Augmented Analytics: The next step for Tableau Varun Tandon, Tableau Solution consultant explained how Tableau is adopting intelligent or Augmented Analytics. Tableau may be moving into adopting augmented analytics for its platform where ML and AI can be used to enhance data access and data quality, uncover previously hidden insights, suggest analyses, deliver predictive analytics and suggest actions, and a lot of other tasks. A lot of users came up with questions and speculations based on Tableau’s acquisition of Empirical Systems last year and whether Ask Data, Tableau’s new natural language capability, a feature included in Tableau 2018.2, was a result of the same. The representatives confirmed the acquisition and also mentioned that Tableau is planning on building analytics and augmented analytics within Tableau without the need for additional third-party add-ons. However, they did not clarify if Ask Data was a result of Empirical System’s acquisition. With Empirical’s NLP module, Tableau users may easily gain insights, make better data-driven decisions, and explore many more features without knowledge of data science or query languages. Doug Henschen, a technology analyst at ConstellationR in his report, “Tableau Advances the Era of Smart Analytics” explored the smart features that Tableau Software has introduced and is investing in and how these capabilities will benefit Tableau customers. Creating a single Hub for data from various sources The conference explained in detail with examples of how Tableau can be used as a single Hub for data coming from various sources such as Netsuite, Excel, Salesforce, and so on. New features on Tableau Prep Builder and Conductor Tableau’s new Data Prep Builder and Conductor, which saves massive data preparation time, was also demonstrated and its new features were explained in detail, in this conference. Shilpa Bhatia, a Customer Consultant at Tableau Software, conducted this session. Questions were asked if Tableau Prep Builder and Conductor would replace ETL. The representatives said that Data Prep does a good job with data preparation; however, users should not confuse it with ETL. They have called the Tableau Prep Builder and Conductor, a Mini ETL. Tableau is also coming up with monthly updates since the tool is still evolving and it will continue for the near future. A question on the ability to pull the data from Data Prep to Jupyter notebook for building data frames was also asked. However, even this isn’t possible with the Prep Prep Builder and Conductor. They said Data Prep is extremely simple to use; however, it is a resource heavy tool and a dedicated machine with more than 16 GB RAM to will be needed to avoid system lag for large datasets. The self-service mode in Tableau Jayen Thakker, Sales Consultant at Tableau explained how one can go beyond dashboards with Tableau. He said, with the help of Tableau’s self-service mode, users can explore and build dashboards on their own without the need of waiting for the developer to build it for them.​ Upcoming Tableau versions The conference also revealed that Tableau 2019.2 is currently in Beta 2 and is expected to be released by the next month. Also, there will be a Beta 3 version before the final release. Each release of Tableau includes around 100 to 150 changes, and a couple of changes were also discussed including Spatial data (MakePoint and MakeLine), some next steps on how it will move beyond ‘Ask Data’ and will include advanced analytics and AI features, and so on. Tableau is also working on serving people who need more traditional reporting, the representatives mentioned.
