The cloning of life remains a deeply controversial and vexing issue due to the ethical implications the technology creates. In reference to literally resurrecting extinct species this creates the introduction of new and alien organisms into a biosphere. Other dangers include the humane treatment as cloning cannot assure the organism may suffer through its creation or if their offspring will be viable and healthy.
The world today is so different, in terms of environment and the extinct mammal such as the mammoth would not necessarily be able to strive in todays world. Cloning extinct mammals might disrupt an ecosystem, if reintroduced after so many years of being absent.
There are some whales that are supposed to be extinct. But some "extinct" animals have been found in deeper waters. There are also ancient marine mamels during the dinosour periods.
Eutherians are a group of mammals consisting of placental mammals plus all extinct mammals that are more closely related to living placentals (such as humans) than to livingmarsupials (such as kangaroos).
The extinct dog-like mammals are from a biological family of carnivorous mainly called Canidae. The Canidae includes almost 34 species from the manned wolf to bush dogs (short in length).
Dinosaurs went extinct and mammals were able to fill the huge ecological niche that was left behind.
Mammals actually first came into existence about 220 million years ago, which is about 155 million years before the dinosaurs went extinct, and only about 10 million years after they themselves first evolved. So mammals actually lived alongside the dinosaurs, though played a much smaller role.
Read "Jurrassic Park" by Michale Crichton. There's your answer
You and I are both mammals, and we are definitely not extinct.
The difference between cloning genes and cloning a mammal is that when a gene is cloned, it is typically removed from a DNA sequence and inserted into an organism. The cloning of a mammal, however, is when a somatic cells from the mammal are cloned to produce a "copy" of the mammal.
Not at all. Mammals are alive and well, and include all creatures with fur/hair and skin. Horses, dogs, cats, mice, kangaroos, bears, etc are all just a small sample of the mammals which are not extinct. Mammoths, on the other hand, were ancient mammals which are now extinct.

there are many ethical problems involved in cloning humans
Not at all. Aquatic placental mammals include dolphins, whales and dugong.
after dinsaurs became extinct
we and all large mammals would not be around
No, not all mammals are placental. There are two other groups of mammals: the monotremes and the marsupials.Monotremes are egg-laying mammals, and marsupials are generally pouched mammals, although not all marsupials have fully developed pouches.
YES! They are mammals so of course
No, Marsupials are not extinct. Some might be endangered, but not extinct. Koalas are marsupial mammals but they are not extinct. Kangaroos are marsupials, not extinct. But some may be extinct.Marsupials are simply pouched mammals, and are very common in Australia.Some extinct species of marsupials include:lesser bilbybroad-faced potoroodesert bandicootdesert rat-kangaroo (not kangaroo rat, which is not a marsupial)Toolache wallabyEastern hare-wallabyCrescent nail-tail wallabyThylacine
