Kangaroo-Monkeys are a mammalian species from the Euarchontoglires super-order. Some basic characteristics of my kangaroo-monkeys include:
- Are excellent bipedal jumpers (they jump from the ground);
- Are obligate carnivores like tarsiers (they are 50% pursuit predators, 35% scavengers, and 15% ambush predators) (they eat other mammals, birds, snakes, arthropods, earthworms, and gastropods);
- Have an average life expectancy of 2.5 decades (25 years), and they age four times faster than humans (a 3 years old kangaroo-monkey is comparable to a 12 years old human);
- Compared to humans, they have an higher risk of heart disease, but a lower risk of cancer;
- Are solitary but social (or as solitary as orangutans if you want);
- Adult males range from 0.91 meters to 1.42 meters (or 3 feet to 4 feet 8 inches if you want), and are 10 % smaller than adult females;
- Have gorilla-level intelligence;
- Have the same hair colour range as fancy rats;
- Have beaver-level strength;
- Have an excellent sense of eyesight, and hearing, and a sense of smell comparable to chimpanzees, but a relatively poor sense of taste (they cannot taste sweet and spiciness, they can taste salt, umami, fat, sour, and bitter).
Given these characteristics, what species could they have evolved from, and what evolutionary pressures would lead to them?
