Some scientists say that the molecular data are likely to be right and that paleontologists need to dig harder for those fossils.
Rhizaria are a major branch of eukaryote evolution with an extensive microfossil record, but only scarce molecular data are available.
Molecular data are equivocal as to whether bats are the sister group to primates and colugos, so these two competing hypotheses cannot yet be tested.
In this review, we summarize the latest developments in this field, focusing on tumor types for which clinically important molecular data are available.
These molecular data are consistent with data from epidemiologic studies that have failed to demonstrate a convincing relationship between exposure to environmental carcinogens and the development of ovarian cancer.
All of this has made phylogenies based on DNA easier to build and helped to highlight the importance of a phylogenetic perspective even when molecular data are unavailable (e.g., for most, but not all, fossil organisms).
The molecular data are compatible with either view, but the weight of evidence suggests placing the great auk in a distinct genus.
Because the differences in molecular data are so minute between the ring-tailed lemur and both genera of bamboo lemurs, it has been suggested that all three genera be merged.
Molecular data are also extremely variable – suggesting that these isolated populations have long been separated.
However, the mixed banteng zebu species origin is not supported by breeding records, while only sporadic molecular data are available [9], [10], [11], [12], [13], [14].
This study highlights the need for an integrative and iterative approach to species delimitation and further makes the point that molecular data are insufficient when interpreted alone.
