Abstract
Increasing numbers of climbers are attempting Mount Everest, the highest mountain on Earth. We compiled interview data and computed the probabilities of summiting and of dying as a function of climber age and gender (2211 climbers, spring season) for the period of 1990-2005. Men and women had similar odds of summiting and of dying. However, climbers older than 40 years have reduced odds of summiting, and those older than 60 years have increased odds of dying, especially when descending from the summit. On Mount Everest, phenotypic selection appears blind to gender but favours young mountaineers.
摘要
越来越多的登山者试图攀登地球上最高的山峰——珠穆朗玛峰。我们收集了访谈数据，并计算了1990年至2005年期间（春季，2211名登山者）登山者登顶和死亡的概率，这些概率是登山者年龄和性别的函数。男性和女性登顶和死亡的几率相似。然而，40岁以上的登山者登顶几率降低，60岁以上的登山者死亡几率增加，尤其是在从山顶下山时。在珠穆朗玛峰上，表型选择似乎对性别不敏感，但青睐年轻的登山者。
