A phylogeny tree can be drawn using Neighbour-joining and/or Maximum Parsimony methods from the mitochondrial DNA and Y chromosome DNA. A known “average face” for each group of ancestor is determined. The mitochondrial DNA of an unknown person is mapped onto the phylogeny tree. The face of the unknown person is reconstructed using “Mendelian Morphing” technique by combining the nearest average faces for each group ancestors on the phylogeny tree. The authors feel this technique can be used for forensic and archeological facial reconstruction/approximation when the skull of skeletal remains is not available. The approximated face is about 60.70% similar (subjective evaluation) to the expected face.

The dung beetles were caught, and their dung balls collected. The beetles were identified as Paragymnopleurus maurus, and their dung balls were identified as originating from Macaca fascicularis, using a molecular approach involving the cytochrome b (Cytb) marker. This is the first record of Paragymnopleurus maurus from the study site in the Langkawi Islands and from this part of Malaysia. Paragymnopleurus maurus is attracted to the omnivorous dung of M. fascicularis, because it is a preferred food source for the beetle. Daytime is the active period for P. maurus and this study shows that the foraging area of P. maurus is restricted to the forest, even though the beetle's food source (M. fascicularis's dung) can be found outside the forest.
