Extreme reversed sexual size dimorphism in the extinct New Zealand moa Dinornis

Article Abstract:

Research has been conducted on moa Dinornis species which dominated New Zealand biota until their extinction 500 years ago. The ancient mitochondrial DNA sequences have demonstrated that these species were indistinguishable within each island, but the use of sex-linked nuclear sequences from an extinct species has demonstrated that on each island the species' morphological forms represented just one species which differed in size according to habitat and sex.

Nuclear DNA sequences detect species limits in ancient moa

Article Abstract:

Research has been conducted on extinct moa. The authors have investigated the sex of these moa via isolation of single-locus nuclear DNA markers, and have tested the hypotheses about moa taxa specific status, and the results have shown the species' extreme reverse sexual dimorphism.

Complete mitochondrial genome sequences of two extinct moas clarify ratite evolution

Article Abstract:

Research is presented concerning the origins of extinct large, flightless birds known as the ratites. The mitochondrial genome sequence of all extinct flightless birds has been used to determine biogeographical data.
