The evolutionary relationships of the avian family Heliornithidae will be determined by solution DNA hybridization and nucleotide sequence comparisons. Alternate hypotheses of heliornithid relationships are predicted differentially by the assumptions of molecular versus morphological and paleontological studies of organismal relationships. The assumptions include, but are not limited to, the correlation of phylogeny and biogeography, the constancy of the rate of evolution of DNA, and the irreversibility of morphological specializations. Resolution of finfoot relationships will test these assumptions indirectly, hence their general applicability to other groups. This study is feasible only because the DNA of some very rare species will be cloned from long-dead museum specimens, demonstrating unforeseen utility of museum collections. Dr. Peter W. Houde will conduct this postdoctoral fellowship research during a two-year tenure period at Princeton University.

鸟类家族Heliornithidae的进化关系将由溶液DNA杂交和核苷酸序列比较确定。 通过分子与形态学和生物学关系的形态学和古生物学研究的假设差异地预测了Heliornithid关系的替代假设。 这些假设包括但不限于系统发育与生物地理学的相关性，DNA进化速率的恒定以及形态专业的不可逆性。 解决方案的关系将间接测试这些假设，从而一般适用于其他群体。 这项研究之所以可行，是因为某些非常稀有物种的DNA将是从长死的博物馆标本中克隆的，这表明博物馆收藏的实用程序。 彼得·W·霍德（Peter W. Houde）博士将在普林斯顿大学（Princeton University）的两年任期内进行这项博士后研究金研究。
