Nephridia of earthworm and malphigian tubules of cockroach belongs to excretory organs. Earthworm has a well developed excretory system which is composed of large number of minute, coiled and glandular segmentally arranged excretory tubules called the nephridia. Malphigian tubules of cockroach are extremely fine yellowish unbranched thread like structure present at the function of midgut and hindgut.

Darwin's Finches are an excellent example of adaptive radiation. Adaptive radiation is the occurrence of the diversification of a single or small groups of species into a large number or descendents that occupy various ecological niches. This is an evolutionary process driven by natural selection.

The theory of the continuity of the germplasm published by August Weismann (1834-1914) in 1886. It proposes that the contents of the reproductive cells (sperms and ova) are passed on unchanged from one generation to the next, unaffected by any changes undergone by the rest of the body. It thus rules out any possibility of the inheritance of acquired characteristics, and has become fundamental to Neo-Darwinian theory.

Peripatus is a genus of Onychophora (Velvet worms). It is said to be a living fossil because it has been unchanged for approximately 570 million years. Peripatus is a nocturnal carnivore. Peripatus is a connecting link between Annelida and Arthropoda. It feeds by trapping its prey (mostly small insects) in a white, sticky fluid it ejects from two antennae near its head. The fluid hardens on contact with the air and then the prey becomes immoblized.
