概要
生物の進化を系統樹で説明するというアイデア自体は古くから見られるものだが，その基礎となる数学は1960～70年代の組合せ論の研究に端を発する．本講演では系統学の基本定理と呼ばれるBunemanの四点条件とそこから広がるcombinatorialphylogeneticsの歴史を概説し，現代の系統学における生物学的な問題意識と数学的な取り組みについて紹介する．
Title : Introduction to combinatorial phylogenetics
Abstract :
The idea of the 'tree of life' is old and dates back at least to Charles Darwin (1837), and the concept of phylogenetic trees appears in areas as diverse as biology, statistics and computer science. However, the mathematical foundation of phylogenetic tree reconstruction was established in 1960/70s when the graph realisability of finite metric spaces was actively studied in combinatorics. In this talk, I will overview how combinatorial phylogenetics evolved since the pioneering work of Peter Buneman (so-called 'four-point condition'), and present some recent biological topics and mathematical results.
