The ancestors of Bromeliaceae originated in the Guayana Shield c. 100 Mya. However, most of the current taxa started to diversify in South America just after the main orogenic changes associated with the beginning of the uplift of the Andes during the Miocene (c. 20 Mya; Givnish et al., 2007, 2011). Since then, impressive diversifications of several functional and ecological adaptations have allowed bromeliads to occupy a range of extreme habitats in almost all of tropical and subtropical South America, and currently species occur from northern Patagonia to the southern USA (Florida); there is also a single species in West Africa (Benzing, 2000; Christenhusz & Chase, 2013). Species from this wonderful monocot family are good models for understanding how the interplay among microevolutionary processes such as gene flow, genetic drift and natural selection influence species-level patterns of macroevolution (i.e. speciation and extinction rates) in the Neotropics.

凤梨科作为了解新热带生物群进化的模型组

凤梨科的祖先起源于瓜亚纳盾c。100妙。然而，目前大多数类群开始在南美多样化正好与安第斯山脉的隆起的中新世（期间开始相关的主要造山带更改后Ç 20妙; Givnish等。，2007，2011）。从那以后，几种功能和生态适应的令人印象深刻的多样化，使凤梨几乎在整个热带和亚热带南美都占据了一系列的极端栖息地，目前的物种从巴塔哥尼亚北部到美国南部（佛罗里达）；西非也有一个物种（Benzing，2000; Christenhusz＆Chase，2013）。来自这个奇妙的单子叶植物家族的物种是理解微观进化过程之间的相互作用的良好模型，这些进化过程如基因流，遗传漂移和自然选择如何影响新热带地区宏观进化的物种水平模式（即物种形成和灭绝速度）。
