... of remains from several individuals suggests that ramidus was not very sexually dimorphic. Presumably, both males and females are represented in the sample, but they all seem to be about the same size. This is in stark contrast to the earliest australopithecines, who were highly sexually dimorphic, so much so that there was once vigorous debate about whether Australopithecus afarensis (Lucy's ...

... expression between the sexes, and microarray studies have documented widespread sexually dimorphic gene expression. Although the evolutionary significance of sexual dimorphism in gene expression remains unresolved ... precise roles of sex-specific selection and sexual conflict in the evolution of sexually dimorphic gene expression are very important. The results of our study and others like it set ...

... The piece he had in the back of his bill prevented him from getting a secure grip on a second nut. Notice I am assuming this was a "he" even though TUTIs are not sexually dimorphic. This just seemed like typical behavior for a male. As he tried, other birds would land on the peanut feeder and he would try to chase them off. Most fled, but not the male red-bellied woodpecker. He parked ...

... has been rescued. We did not see it again. I emailed our local IFAS office for help confirming the identification. He wrote that it is a marbled salamander, Ambystoma opacum . He said that they are sexually dimorphic: the females have grey or silver markings, while the males have white. Well, our jury is out on this call. It seems to be rather silver in the water pictures and white in the net. ...

... members of the Reproductive Toxicology Branch of the EPA did not find any evidence that Bisphenol A (BPA), was a "gender bender" in female rats. BPA "Does not Alter Sexually Dimorphic Behavior, Puberty, Fertility and Anatomy of Female LE Rats" (Abstract here, via Stats.org) This is particularly good news in the light of the Consumers Union's recent report that showed ...

... ’t grasp the female properly. After several tries, the male realised its mistake and released the female. Both Neurothemis fluctuans and Trithemis aurora are very common species here. Both species are sexually dimorphic. Mature N. fluctuans males are reddish while the females are light brownish. For T. aurora, mature males are pink while females are yellowish. Pictures taken at: Singapore ...

... . The inset article (circa 1901) explains a situation that should never have happened. Sadly it did. These beautiful birds are now extinct. They were called the Huia. The male and female were sexually dimorphic. The female had a longer and markedly curved beak and was also larger than the male. These birds mated for life and once inhabited Northland where I live. By the time settlement arrived in ...

... controls sex comb position. Scr in pupa; stages is only expressed in a limited domain in the leg, and ectopic expression of Scr produces multiple sex combs. Expression is also sexually dimorphic, with no upregulation of Scr in female legs. In D. ficusphila, which has enormous sex combs, Scr levels are elevated yet further to 7 times the levels found in D. willistoni. The sex determination ...
