Very first, a couple primitive animals (opossum and you will platypus) and another bird (chicken) is demonstrably not the same as other mammals

I used a system to exhibit brand new proportions out-of common genetics one of punctual-changing and you will slow-developing genes anywhere between pairs out of mammals (Figure step three). Second, primates are also closely clustered with each other. 3rd, mouse functions as an effective middle that links cow, horse, guinea-pig, rat, and you will opossum. Fifth, specific connections ple, fast-evolving family genes shared by puppy, pony, and you may macaque also sluggish-changing genetics shared by cow, macaque, orangutan, and you can chimp.

A system of timely-developing and you will slow-developing family genes one of several mammalian variety. The a few considering types, we determined the new shared quantity of timely-changing otherwise sluggish-changing family genes and you may subsequently divided him or her according to the overall mutual quantity of family genes to help you normalize the fresh new relationship coefficients. We linked the fresh new varieties in line with the largest one or two relationship coefficients for each and every couples. Red-colored and eco-friendly traces stand for timely-evolving and you can sluggish-evolving genetics, correspondingly, and red-colored outlines may be the amount of one another.

I up coming examined the brand new private properties of quick-growing and you may sluggish-changing genes when you look at the around three mammalian lineages: primates (chimp, orangutan, and you may macaque), highest animals (horse, canine, and you will cow), and you can rats or rodents (guinea-pig, mouse, and you may rat; Table dos, 3, and 4).Läs mer »Very first, a couple primitive animals (opossum and you will platypus) and another bird (chicken) is demonstrably not the same as other mammals
