What are some potential dangers of cloning extinct mammals such as the mammoth?
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.
Buffalo is known for its rich history as a major industrial and transportation hub in the United States, for its architectural treasures such as the Frank Lloyd Wright-designed Darwin Martin House, and for its iconic Buffalo chicken wings, which were invented in the city in 1964.
What family of mammals is the only one to have members who live on land in trees and in the water?
The family of mammals that fits this description is the Mustelidae family, which includes animals like otters and weasels. These animals are versatile in their habitats, with some species like otters being semi-aquatic and others, like weasels, being skilled climbers that can also live on land.
Is a bird a mammal or reptile?
Dinosaurs evolved from an earlier group of reptiles, and birds evolved from a group of dinosaurs.
One of the earliest birds, Archaeopteryx, dates back to the Jurassic. It has many features of dinosaurs, and indeed, several fossils of Archaopteryx were initially mistaken for dinosaur fossils. It is fairly clear from the fossil evidence that birds evolved from dinosaurs.
Dinosaurs themselves date back to the middle to late Triassic. You may wish to look up Eoraptor. Dinosaurs appear to have evolved from socket-toothed archosaurs common in the mid Triassic, which were an early reptile.
The skeletal structure of dinosaurs bears many similarities to that of birds. Birds are classified as dinosaurs, while all "non avian" dinosaurs went extinct at the end of the Cretaceous.
Answer:That may depend on the dinosaur. All dinosaurs are likely to have ultimately evolved from reptiles, but the theropods (bipedal carnivorous dinosaurs) may have evolved from ancient birds. Birds have many features in common with theropods which suggests that they had a common ancestor. It is generally believed that this common ancestor was a dinosaur but it may well have been a bird (see related links).Looking back in time through the theropod fossil record, these dinosaurs appear to be more bird-like the further back in time you look. Raptors are known to have had feathers and were fairly bird-like, but Archaeopteryx was much more bird-like and lived much earlier and may have been an ancestor of the raptors. There is also a controversial fossil called Protoavis that was dated even earlier and was more bird-like still, with hollow bones like modern birds.
So birds may have been around throughout the mesozoic era and pre-date the dinosaurs. We have little record of them though because their more fragile, hollow bones reduce the chances of any fossils surviving to the present day.
What is a mammal called that feeds on invertebrates?
Often, mammals (and other animals) that feed on invertebrates are called insectivores because they feed primarily on insects.
Apart from these, there are several mammals that feed on invertebrates. Monotremes commonly do so, and these are the platypuses and echidnas. Many small dasyurids (carnivorous marsupials) also feed on invertebrates. These include animals such as phascogales and numbats. Other mammals that feed on invertebrates include anteaters and hedgehogs.
How do mammals excrete there waste products?
Okay, the answer i got for this question was that mammals excrete in two ways. The first was in during the digestive system, It simply means that the waste goes through the body and out the anus. The other way is that they go through chemical waste. This means whenever a mammal breathes for example, you breathe in air but you must breathe out the chemical carbon dioxide from the body.
Bats are the only flying mammals. There are also flying lizards, snakes, and squirrels, but they actually glide from one place to a lower point.
What birds are considered mammals?
No birds are mammals. In fact, birds are of a different kind of category, called "aves". Some scientists say that this is just another branch of the reptiles, but some say birds are different.
What mammals grow hair only after they are born?
Only mammals that have hair their whole lives are naked mole rats; this is because their hair doesn't go through a shedding process. Other mammals, like humans and chimpanzees, start growing hair immediately after birth.
What is meaning of Small Mammals?
Small mammals refer to a diverse group of animals that are relatively small in size and have fur or hair. This category includes rodents, shrews, rabbits, and some small carnivores like weasels and martens. Small mammals play important roles in various ecosystems as prey for larger animals, seed dispersers, and ecosystem engineers.
What are some environments that placental mammals live on?
Placental mammals live in almost every environment on Earth. They are one of the most successful groups in the animal kingdom. Mammals in general are very successful and the majority of mammals are placentals. This group is so successful because they are endothermic. The only mammals that are not placentals are the marsupials (kangaroo, opossum, etc) and the prototherians (egg laying mammals). Environments that do contain mammals would likely be constrained to those that are very severe: The deep ocean, extremely high mountain peaks, etc. Otherwise you can find these animals almost anywhere.
Why does the heartbeat of mammals's make a sound?
In all mammals, the heart is double pump. Each side of hte heart has an upper and lower chamber. The top chamber are called atriums and lower chamber are called ventricles. A one way flap called a valve connects the upper and lower chambers. when the heart muscle relaxes, blood flows through the open valves from the atriums into the ventricles. when the heart contracts, the flap is closed with a thump. the valve prevents the blood from moving back into the the atrium, and it is forced out of the heart through another opening. The sound from the valves can be heard through the tissues of the body and is often described as a lub-dub sound. I hope this helps everyone my son did this project for his science fair at Pioneer Academy of Science, Clifton NJ . Great project

What mammal has the highest population?
The mammal group with the highest population is the mouse. With an estimated 30 per every human on earth, that means there are approximately 210 billion mice on the planet.
The single mammal species with the highest population would be Humans. Cows number approximately 1.3 billion. Dogs number 500 million, cats number 300 million. In short, the animals whose specie has the highest numbers are the ones with the most importance to humans.
Outside of rodents, chickens have the largest population with 24 Billion.
What is the most common mammal in the world?
Some people would say humans, but there are only about six billion of us. I would suggest that it would be either an animal that is useful to us (ie. sheep, cattle) or a rodent. My best guess would be the rat or mouse.
How do mammals breathe underwater?
Mammals cannot breath water. Dolphins, whales, seals, walruses, and other aquatic mammals all have lungs and breath air. They seem as if they are breathing water because of the assumption that they have to breath as often as we do. However, aquatic mammals can actually hold their breath much longer, ranging from around 10min for a walrus to over an hour for some whales.
The reason they can do this has to do with the construction of their lungs and the Diving Reflex, which slows heart rate (among other things).
Mammals, such as whales and dolphins, have to hold their breath while underwater. They all have lungs and breath air and would drown if they tried to breath underwater. However, they can hold their breath for a long time (over an hour for some whales).
What is a mammal that carries their young in pouches?
A kangaroo is an example of a mammal that carries their young in a pouch. The joey, or baby kangaroo, develops inside the mother's pouch after being born extremely premature.
What is the hairy mammoth scientific name?
The scientific name for the woolly mammoth is Mammuthus Primigenius. A partial taxonomy for mammoth is:
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Proboscidea (long snout)
Family: Elephantidae (elephants and mammoths)
Genus: Mammuthus
There are several species within the Genus:Mammuthus, one of which is the woolly mammoth.
What is the scientific name for egg laying mammals?
Egg laying mammals are monotremes. They belong to the order monotremata.
Yes, a cat is a placental mammal. Placental mammals are a group of animals that give birth to live young, nourished through a placenta during gestation. Cats fall into this category as they exhibit this reproductive mechanism.
When did humans and mammals appear on earth?
The first true mammals appeared on Earth around 200 million years ago, in the late Triassic period. However, these mammals would remain small and relatively insignificant due to the dominance of the dinosaurs. Only when they died out 65 million years ago did mammals grow and diversify to become the ones we see today. The first modern humans (Homo sapiens sapiens) evolved around 200,000 years ago.
That is correct. Mammals are characterized by features such as having body hair, giving birth to live young, and producing milk to feed their offspring. Humans share these characteristics with other mammals.
Yes, a human being is a mammal. Mammals are a group of vertebrate animals that have mammary glands to nurse their young, hair or fur, and typically give birth to live young. Humans possess all these characteristics, making them mammals.
