1. The document discusses using phylogenetic methods from evolutionary biology to model and analyze the diversification and development of languages over time.
2. These methods allow for quantitative dating of language relationships and splits, accounting for uncertainty and factors like borrowing between languages.
3. When applied to Indo-European language data, phylogenetic analysis strongly supports an Anatolian origin for Proto-Indo-European around 8000BP rather than the Kurgan hypothesis.
Towards inferring the history of life in the presence of lateral gene transfe...boussau
Short presentation given at Evolution 2014 (similar to that given at SMBE 2014). Introduces a new method for estimating a species tree in the presence of gene duplication, loss, and lateral gene transfer, in a statistical framework, based on a large number of gene families. Results on simulations and real data are presented.
Overview of the approaches I co-developed to reconstruct species trees and gene trees, in the presence of gene duplications, losses and transfers, or incomplete lineage sorting. Includes Phyldog, ALE, MP-EST*, RevBayes.

● Glacial refugia remain controversial as a mechanism of neotropical speciation
● We estimate ancestral areas and simulate diversification rates to test neotropical Pleistocene refugia
● Null models of constant speciation and extinction rates always show more speciation events in the Pleistocene ● The age of extant sister species fails to test glacial refugia as a mechanism of speciation
● Instead, testing the Pleistocene refugia hypothesis requires modeling diversification rates through time
Models of gene duplication, transfer and loss to study genome evolutionboussau
Presentation of the models of gene duplication, transfer, loss, and incomplete lineage sorting developed by my colleagues and myself. Results on gene tree inference, species tree inference are presented. Groups of species studied include mammals, birds, fungi and cyanobacteria.

Modeling the biosphere: the natural historian's perspectiveRutger Vos
Natural history collections of specimens are a rich source of data for discovering the patterns of biodiversity in space and time and for furthering our understanding of the underlying processes that generate these patterns. Modeling the biosphere in this manner can help address global challenges in relation to climate change, food security, emerging disease and conservation. (Talk to the 3rd annual eScience symposium, 8 October 2015).

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
