Answer:
Elliptical galaxies, such as M87 have very little gas and dust. ... Both the largest and the smallest known galaxies are elliptical. Very large elliptical galaxies can reach 300 million light years in diameter. Dwarf ellipticals, which are very common, may contain only 1/100,000th as many stars as the Milky Way!
Most spiral galaxies contain a central bulge surrounded by a flat, rotating disk of stars. The bulge in the center is made up of older, dimmer stars, and is thought to contain a supermassive black hole. Approximately two-thirds of spiral galaxies also contain a bar structure through their center, as does the Milky Way.

What is phylogeny?
Phylogeny is the study of a species' or group's evolutionary history, particularly as it relates to relationships and lines of descent among large groups of animals.
The idea that distinct species of plants or animals descended from a single ancestor is fundamental to phylogeny and is widely recognized in the scientific community. Since the majority of animals that have ever existed are extinct and only a small portion of their fossilized remnants have been preserved in the fossil record, the evidence for these relationships is almost always insufficient. Therefore, the majority of phylogenies are based on inferential data and are hypotheses. Commonly, different phylogenies can be inferred from the same evidence.
