There are a number of animals that are known to be solitary animals, and thus, are pretty disloyal. However, the animal that is considered to be the least loyal would be the Tasmanian devil.
Mammals

Kangaroo is least like the others because it is a marsupial, while the others are all hoofed animals.

No, not closely at least.
Thesus monkey is the most closely related to Humans because it has the least number of differences in cytochrome c.
Yes. At least, it is closely related.
I would think that if they were closely related, they would at least be a cross of the same breed.

cone, is related to gymnosperms; the other three terms are related to angiosperms
Perissodactyls (odd-toed ungulates like horses and rhinos) and Carnivora (carnivorous mammals like cats and dogs) are least closely related to artiodactyls in terms of evolutionary history and morphological characteristics.
The incorporation of meat and marrow from large animals, which occurred by at least 2.6 million years ago.
Based on the comparison of DNA, the animals most closely related to humans are Chimpanzees, Bonobos, Gorillas, and Oranutans. Of those, the Chimpanzee has the least variation from HumanDNA.
No, dolphins did not evolve from men, no other species evolved from men. Dolphins are small whales. The closest land animal to the whale is the hippo. Or at least that is the current theory. So dolphins are more closely related to horses, cows, sheep, and deer than they are to people.
Genes, to a large degree, determine how animals behave towards one another. In two closely related animals, it is more than likely that both animals carry a copy of the same gene. If that gene causes the animals to behave altruistically towards one another, it is in fact increasing the chances of survival of at least one copy of itself.
