Elephantiasis occurs in the presence of microscopic, thread-like parasitic worms such as Wuchereria bancrofti (the most common), Brugia malayi, and Brugia timori (also known as B. timori), all of which are transmitted by bites from infected mosquitoes.Infections usually begin when people are children.he worms are spread by the bites of infected mosquitos. Infections usually begin when people are children. There are three types of worms that cause the disease: Wuchereria bancrofti, Brugia malayi, and Brugia timori.
An analogous structure is a structure that has a similar function but different components. For example, the wings of a butterfly verses those of a bird. In both cases, the fu â¦ nction is flight, but the wings are build differently.
When the structures are homologous, they have similar functions and have a common ancestry in evolution. When the structures are analogous, they have similar functions but hav â¦ e a different evolutionary origin.nalogous structures are structures that are similar in appearance and function but are not the result of shared ancestry. For example, the wings of a birds and insects have the same function, but they do not reflect a shared ancestry. + 30 others found this useful.
