Homo sapiens is the species name of anatomically modern humans and the only living species of the genus Homo. There have been several distinct but extinct species and subspecies identified in the fossil record. Homo sapiens evolved most recently from Homo erectus, which was very similar anatomically...
Did Homo sapiens breed with Homo heidelbergensis? Were Homo heidelbergensis the same as Homo erectus? Was Homo naledi a direct ancestor to Homo sapiens? Did Denisovans and Neanderthals come in contact? Did Homo sapiens eat Neanderthals? Do Homo sapiens have any subspecies? Why is there no mitocho...
There’s no doubt that humans exhibit many characteristics of apex predators, particularly in terms of their position in the food chain and their impact on ecosystems. But, they also diverge from the traditional apex predator profile in significant ways. Their use of technology and diverse diet s...
And given resent data from relatively big sample of 131 chimpanzees, represented three subspecies (Pan troglo- dytes verus, P. t. schweinfurthii, P. t. troglodytes), fWHR may not be considered as sex-related trait in this species either [97]. To what extent facial dimorphism, particularly ...
Adherents to this view typically assign humans and Neanderthals to separate subspecies, Homo sapiens sapiens and Homo sapiens neanderthalensis, respectively. Race is a tricky topic in anthropology. When we look at human biological variation, there is no single pattern of variation that divides humans...
Materials and methods Honey bee tissue collection. Honey bees represent a typical mix of Apis mellifera subspecies found in North America. They were collected from the landing board of outbred colonies in New York, New York at different times during the months of April–October. Only ...
It isn’t known exactly whenCanis lupus(the wolf) morphed into the subspeciesCanis lupus familiaris(the domestic dog), although it is probably more than 30,000 years ago. The change presumably arose through cooperation in hunting. This would require the building of trust betwee...
(there are also subspecies sometimes). These arelonely nit-picky peoplewho argue amongst themselves and lose sleep at night worrying whether or not dolphins are whales. Well, actually, what they really worry about is the confusion that is caused by every day non-whale biologist ordinary Joe's...
Following standardisation to mt-tRNALeu(UUR) levels, a 70% reduction in mature mt-tRNA- Ser(AGY) steady-state levels was determined in the patient's cells relative to age-matched controls (Figure 5a). Interestingly, a seemingly smaller subspecies of mt-tRNASer(AGY) was also detected in ...
Below are the six semantic classes of assertions and the six different dia- grams into which all assertions can be fitted. When we discuss the types of formal structure, in the next chapter, there will be a second set of diagram- matic distinctions, and when we discuss modification, there ...
