对于Mike Steel和David Penny提出的一个猜想,即任何涉及N个类群的系统发育都可以明确地恢复,我们给出了一个显式构造,该猜想使用了对数、 、N个二进制数和最大简约度的方法。从生物学上讲,这意味着同质性不一定是对简约方法的威慑。同源关系的一些模式具有系统发育信息性,可以指数级地减少解析系统发育所需的数据量。
We give an explicit construction to solve a conjecture of Mike Steel and David Penny that any phylogeny involving N taxa can be recovered unambiguously using on the order of log N binary characters and the method of maximum parsimony. Biologically, this means that homoplasy need not be a deterrent to parsimony methods. Some patterns of homoplasy are phylogenetically informative and can exponentially reduce the amount of data needed to resolve a phylogeny.
