Supraprimates, Laurasiatheira, Xenartha, and Afrotheria. Supraprimates evolved into primates, colugos, tree shrews, rodents, and lagomorphs (rabbits, hares, and pikas). Laurasiatheria evolved into pangolins, carnivores, odd-toed ungulates, cetaceans (whales, dolphins, and porpises), even-toed ungulates, bats, erinaceomorphs (hedgehogs, gymnures, and moonrats), and soricomorphs (shrews, moles, and solenodons). Xenartha evolved into armadillos, anteaters, and sloths. Afrotheria evolved into elephants, sea cows (manatees and the dugong), hyraxes, the aardvark, elephant shrews, tenrecs, and golden moles.
Both are four legged placental mammals. Other than that, they are not related at all.
No. They're mammals, like you & me. Guinea Pigs have spines, which makes them vertebrates, not invertebrates.
There are four main groups of mammals: monotremes, marsupials, placental mammals, and the recently recognized group of egg-laying mammals. Monotremes, like the platypus, lay eggs, while marsupials, such as kangaroos, give birth to underdeveloped young that typically continue developing in a pouch. Placental mammals, which include humans and most other mammals, carry their young in the womb until they are more fully developed. Each group exhibits unique reproductive and developmental traits.
The four-chambered heart is not a poor choice for phylogenetic trees; it is actually a shared feature among mammals and some birds. Its presence in a wide range of species suggests a common evolutionary ancestry, making it a useful trait for tracing evolutionary relationships.
They're armoured mammals of the family Dasypodidae.
Mammary glands (in adult females), a neocortex (a region of the brain), a corpus callosum (another region of the brain, in placental mammals only), and the malleus and incus middle ear bones.
Echidnas belong to the group of mammals known as monotremes. They are mammals that lay eggs, as opposed to placental mammals, which give birth to live young. (Marsupials - pouched mammals - are also placental mammals.) Their order is "monotremata", and there are only five living monotreme species: the platypus and four species of echidna (also known as spiny anteaters). All of them are found only in Australia and New Guinea.
Cats are mammals. The only mammals which lay eggs are the monotremes. The only surviving examples of monotremes are all indigenous to Australia and New Guinea, although there is evidence that they were once more widespread. Among living mammals they include the platypus and four species of echidnas (or spiny anteaters). There are no feline monotremes. Cats cannot lay eggs.
Extinction events, such as the Permian extinction and the KT extinction event. You have adaptive radiation driving evolutionary change after such events. Google " the rise of the mammals. "
Quokkas a mammals, like humans, so they share various mammalian traits. These include feeding their young on mothers' milk, having hair, breathing through lungs and having a four-chambered heart. However, quokkas are marsupials while humans are placental mammals, so when it comes to reproduction, they are very different.
The answer to this is not based on where the animal lives but on the type of animal. Animals that lay eggs have fewer extraembryonic membranes than placental mammals...there are mammals in the ocean as well as on land.
Egg-laying mammals are known as monotremes, and they include the platypus and the echidna. Their characteristics are:unlike placental mammals and marsupials, they do not give live birth, but lay eggs in order to reproducemonotremes nurture their young with mothers' milk as all mammals dothey have four limbsthey are warm-blooded vertebratesthey have a four-chambered heart
