Chimps are the champs when it comes to tool use, e.g. Q6.8. They also have smaller wings that reduces their weight while under the water. They have long claws on their toes. The word duck comes from Old English dce 'diver', a derivative of the verb *dcan 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch duiken and German tauchen 'to dive'.

[9], In most modern classifications, the so-called 'true ducks' belong to the subfamily Anatinae, which is further split into a varying number of tribes. Latin anas "duck", Lithuanian ntis 'duck', Ancient Greek / (nssa/ntta) 'duck', and Sanskrit t 'water bird', among others. [12] The 'sea ducks' of the tribe Mergini are diving ducks which specialise on fish and shellfish and spend a majority of their lives in saltwater. While most ducks share many characteristics and they are all members of the Anatidae bird family, the exact number of species varies depending on how each bird is classified. Mother ducks are very caring and protective of their young, but may abandon some of their ducklings if they are physically stuck in an area they cannot get out of (such as nesting in an enclosed courtyard) or are not prospering due to genetic defects or sickness brought about by hypothermia, starvation, or disease.

Dabbling Duck Dabbling ducks are easily recognizable by their trait of sticking their rump out of the water while they feed. While we cannot swing by our arms as well as the lesser apes (brachiation is the technical term), we great apes retain the suspensory hanging adaptation and can swing to varying degrees, as long as the tree will support us. Ducks' nests are raided by land-based predators, and brooding females may be caught unaware on the nest by mammals, such as foxes, or large birds, such as hawks or owls. It classifies organisms based on descent from a common ancestor, using similarities in physical characteristics. Darwin, evolution, & natural selection (article) | Khan Academy Diving ducks and sea ducks forage deep underwater. These may get introduced in an ecosystem by, R and K selection are concepts in ecology used to describe traits in the fluctuation of a population or population dynamics. A common urban legend claims that duck quacks do not echo; however, this has been proven to be false.

The amount of webbing on a duck's feet is a heritable trait. Evolution: Library: Adaptive Radiation: Darwin's Finches - PBS The ancestor of the great apes was an arboreal climber. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. The amount of webbing on a duck's feet is a heritable trait. They have webbed feet which makes them fast swimmers.

While a commercial strain of White Leghorn will produce 250-280 eggs per year, commercial egg producing ducks will produce 300-350 eggs per year! One leads to allopatric speciation, occurring, and the other does not. The Mandarian Duck (Aix galericulata) and its relative the Wood Duck (Aix sponsa) are also domesticated, but far less common than Mallards or Muscovies. Great ape social organization varies by species. Biologists believe that ducks evolved from land birds, which did not have webbed feet. The body shape of diving ducks varies somewhat from this in being more rounded. Dabbling ducks are also called dipping, surface-feeding, or freshwater ducks. males bite one another!

They were therefore able to eat aquatic plants and get enough food to survive and reproduce. [41] It is probable that duck eggs were gathered by Neolithic hunter-gathers as well, though hard evidence of this is uncommon. Individuals of this The more they used their feet, the more webbed their feet became, so they got enough food to survive and reproduce. 12.
