For Lewis, the House is a way of "connecting dots" – joining people to their past, understanding how identity is a blend of culture, geography and genealogy, a collision of unique traits and common bonds.
In addition to those traits they have in common with non-snake lizards, snakes are often separated from other lizards in popular literature because they share a set of unique traits that are relatively easy to observe.
These resemble the remains of Neanderthals (H. neanderthalensis) in having some rugged features (e.g., browridges), but they do not have the entire suite of unique traits that characterize Neanderthals.
Nevertheless, such a population size would be sufficiently small for a set of unique traits to become established, making it plausible that one small group would be the population from which H. sapiens emerged as a new isolated reproductive entity.
It is quite distinct from other oryzomyines and has a number of unique traits.
The complex genetic nature of unique traits of Basmati as well as tedious screening methodologies involved in quality testing have been serious constraints to breeding quality Basmati.
The ability to induce and sustain genomic copy number changes following FN mutagenesis expands our understanding of the potential mechanisms that underlie the recovery of unique traits in mutant populations.
The schizothoracine fishes dominate the plateau lakes and torrential mountain streams of the Tibetan Plateau (He and Chen 2006) and have evolved a number of unique traits to adapt to the hypoxia and cold environment (Wu Y and Wu C 1991).
However, brown trout are under pressure from habitat destruction, pollution, over-exploitation and stocking with non-native fish, i.e. local factors that may erode the high levels of genetic variation observed and cause the extinction of unique varieties and loss of unique traits (Ferguson 1989).
Factors that need to be considered when defining such priorities include the importance of a breed in terms of genetic uniqueness but also its own genetic diversity, and other aspects such as adaptation to specific environments, possession of unique traits, cultural and historical value, contribution to environmental sustainability, etc. [ 58].
