I believe this picture adds to the American Robin article in that it is the only picture showing a robin feeding. It also shows how the Robin's coloring helps it blend in with the broken/patchy light under a bush. Articles this image ...
Chaetopterus pugaporcinus, commonly known as the pigbutt worm or flying buttocks, is a species of worm first described by scientists at the Monterey Bay Aquarium Research Institute in 2007. [1] The worm is round in shape, approximately 10 to 20 millimeters in length (roughly the size of a hazelnut ), and bears a strong resemblance to a ...
Thus each worm becomes the genetic father of some of their offspring (due to its own sperm transferred to other earthworm) and the genetic mother (offsprings from its own egg cells) of the rest. As the worm slips out of the ring, the ends of the cocoon seal to form a vaguely onion-shaped incubator in which the embryonic worms develop. Hence ...
Gongylonema pulchrum was first named and presented with its own species by Molin in 1857. The first reported case was in 1850 by Dr. Joseph Leidy, when he identified a worm "obtained from the mouth of a child" from the Philadelphia Academy (however, an earlier case may have been treated in patient Elizabeth Livingstone in the seventeenth century [2]).
Amynthas agrestis, the Asian jumping worm, [note 1] is a species of worm in the family Megascolecidae. [1] It has a smooth, glossy, grey or brown body with a milky-white clitellum , [ 2 ] and can range from 1.5 to 8 in (3.8 to 20.3 cm) in length. [ 2 ]

Some species within the Arctiinae have the word "tussock"' in their common names because they have been misidentified as members of the Lymantriinae subfamily based ...
This, however, conveys a reduced if not false picture of Darwin's theory in which competition, hereditary transmission, coincidence and selection play a major role. [9] Besides, these circular images of evolutionary progression form a striking contrast to Darwin's own linear and branching evolutionary trees.
