Rate variation during molecular evolution: creationism and the cytochrome c molecular clock [PDF]

open access: yes, 2017
Molecular clocks based upon amino acid sequences in proteins have played a major role in the clarification of evolutionary phylogenies. Creationist criticisms of these methods sometimes rely upon data that might initially seem to be paradoxical.

Splicing of group II introns in mRNAs coding for cytochrome b6 and subunit IV in the liverwort Marchantia polymorpha chloroplast genome Exon specifying a region coding for two genes with the spacer region [PDF]

open access: yesFEBS Letters, 1987
Two genes, petB and petD, encoding cytochrome b 6 and subunit IV of the cytochrome b 6/ƒ complex, respectively, of the chloroplast genome of Marchantia polymorpha, a liverwort, have been mapped between the psbH and rpoA genes and each of the petB and petD genes has been predicted to contain a group II intron in its coding sequence [(1986) Nature 322 ...

PHYLOGENY OF THE PEROGNATHUS LONGIMEMBRIS SPECIES GROUP BASED ON MITOCHONDRIAL CYTOCHROME-b: HOW MANY SPECIES? [PDF]

open access: yesJournal of Mammalogy, 2005
The Perognathus longimembris species group currently consists of 3 species and approximately 23 subspecies. Members of this species group have been of considerable interest to biologists in both physiological and ecological studies, and several members are threatened with extinction.

Species Limits and Phylogeography of North American Cricket Frogs (Acris: Hylidae) [PDF]

open access: yes, 2008
Cricket frogs are widely distributed across the eastern United States and two species, the northern cricket frog (Acris crepitans) and the southern cricket frog (A. gryllus) are currently recognized. We generated a phylogenetic hypothesis for Acris using

Phylogenetic relationships and karyotype evolution in the sigmodontine rodent Akodon (2n = 10 and 2n = 16) from Brazil

open access: yesGenetics and Molecular Biology, 2006
Comparison of G-bands from 2n = 10 and 2n = 16 karyotypes of Akodon revealed tandem fusions, pericentric inversions and Robertsonian rearrangement in autosomes and addition/deletion of constitutive heterochromatin in sex chromosomes.
