Turnstone traits are apomorphic and plesiomorphic, it may be an ancestral representative of either lineage. Turnstone Turnstones are two bird species that comprise the genus Arenaria in the family Scolopacidae. They are closely related to calidrid sandpipers and might be considered members of the tribe Calidriini. The genus name "arenaria" is from Latin "arenarius", "inhabiting sand", from "arena", "sand". Both birds are distinctive medium-sized waders. Roughly speaking, length is typically between 20 and 25 cm, with a wingspan between 50 and 60 cm and a body mass between 110 and 130gm. For waders their build is stocky, with short, slightly upturned,
Insertion sort elements of the unsorted input, while in insertion sort they are simply the first "k" elements of the input. The primary advantage of insertion sort over selection sort is that selection sort must always scan all remaining elements to find the absolute smallest element in the unsorted portion of the list, while insertion sort requires only a single comparison when the "k"+1th element is greater than the "k"th element; when this is frequently true (such as if the input array is already sorted or partially sorted), insertion sort is distinctly more efficient compared to selection sort. On average (assuming the
