The more they used their feet, the more webbed their feet became, so they got enough food to survive and reproduce. species reproduce. While gorilla tool use had been known from observations of gorillas in captivity, the use of a tool in the wild was finally recorded in 2005 when a female used a stick to test water depth. The Mandarian Duck ( Aix galericulata) and its relative the Wood Duck ( Aix sponsa) are also domesticated, but far less common than Mallards or Muscovies.

Understand how studying non-human primates is important in anthropology. be reproductively isolated from other members? They go upside-down, instead of diving, to eat insects or weeds. Evolution is not goal directed it simply track their changing environment with adaptations that maximize their reproduction in a particular environment at a particular time, Movement of individuals away from one another, an individual that has more than two chromosome sets that are all derived from a single species, Geographical separation typically a physical barrier such as a river, resulting in a pair of closely related species, A reproductive barrier that impedes mating between species or hinders fertilization if interspecific mating is attempted, A group of organisms that are closely related and can mate to produce fertile offspring. [6][7] The number of suggested subfamilies containing ducks ranges from two to five. Low precipitation [5] All except the screamers belong to the biological family Anatidae.

They were therefore able to eat aquatic plants and get enough food to survive and reproduce. Biologists believe that ducks evolved from land birds that did not have webbed feet. They are quick and can also dive if needed. The wings are very strong and are generally short and pointed, and the flight of ducks requires fast continuous strokes, requiring in turn strong wing muscles. The illustration below shows the morphological change of two species The shape of the parent ducks feet 3. different geographical areas reproduce 1.

"Survival of the fittest" is more prolific (productive, more offspring) reproduction of individuals with favorable traits that survive environmental change because of those traits; this leads to evolutionary change, (biology) an organism that has characteristics resulting from chromosomal alteration, difference between individuals in the same species, Heritable trait that helps the survival and reproduction of an organism in its present environment, When two species evolve in diverse directions from a common point, Similar traits evolve independently in species that do not share a recent common ancestry, Chromosomes that have the same sequence of genes and the same structure.
