Extinct Animals

American lions are once said to be the biggest cat species living on earth, bigger than the african liger or the siberian tiger. Males can grow to be 5 ft tall at the shoulder, be up to 12 ft long, and weighs up from 700 pounds to 800 pounds. Females are 25 percent the size of males.
the American lion stood 5ft tall to the shoulder and was about 11.5 feet long not including its 4.3ft tail

Make a difference!

Animals are becoming extinct because people will cut down the forests and they will not take care of the earth, they just ruin it. I am not a part of this horrible creation of a mess. I recycle batteries, cardboard, and lots of other stuff. People should stop taking oil out of the earth; it isn't fair to the earth, because the earth can't put up a fight besides putting the oil way down deep in its crust. I think we should leave and die out, or get to work and fix as much as we have destroyed.

No one or anything should be treated how we have been treating the earth. My favorite animals are elephants and they are endangered because we give them nowhere to live that they can work with. We take their land and we used to kill them for their tusks. It is not right. No one should be killed because they have something someone else wants. No one should be killed because we humans are greedy. Some of us try to protect the elephants and all the endangered species and I am proud of them for helping the earth and not just helping themselves to anything the earth puts on the table for us to share with everything living. Most of us humans need to learn to share the earth and not just leave it there to pick off of until it can't hold are greed and it dies out.

The earth cannot hold us forever soon enough no one will free. There will either be no government and everyone is living on the streets half dead with no one to take care of them because they are either dead or just lost. Or the government controls how much we eat, when we sleep, how long we work, and the government will no longer care if we die out because they have a secret place where everything is perfect and safe or they just won't plain care. People will no longer know the difference between right and wrong no one will care if you commit suicide or just die. People will beg the people with food for some or they will just murder them and take it. No one will be the same, people can change and the world can die out.

We could find a place to live right now and get ready pack up and leave everything with the animals and all the other living things. But, I highly doubt that will happen I bet we will live here for as long as possible. And, when we have destroyed the earth as much as possible, then we pack up and leave. Then we get to the other world and we ruin that place. After that, we just keep going and make a difference. The people that help the earth can either make a difference. Or the world will be one of the things I just said.

The dodo and the tazmanian tiger to name two. i am sure there are more.
There are many animals that were alive 200 years ago, but are now extinct.

The last known living passenger pigeon died in 1914.

The golden toad

Great Auk

Blue Walleye

The quagga is a recently extinct subspecies of the Plains zebra. Unlike other zebras, with their full-body black and white stripes, the quagga was striped only on the front part of its body, with its hindquarters a solid, darker brown. The stripes on its head faded to a yellow-ish brown body and made for a creature with a very unique set of markings.

a prehistoric tiger with large sharp teeth ---- There were several species of extinct sabre-toothed felines (cats). They originated in an epoch called the Oligocene (almost 40 million years ago) and persisted until just over 11,000 years ago. The largest (called Smilodon) is, I'm pretty sure, the sabre-toothed tiger that you're referring to. Smilodon roamed the US western plains and California and was probably contemporary with ancient humans. It had canines that were as long as 7-8 inches and weighed more than 400 pounds, which is about the size of the male African lion.

By the process of natural variation and selection by survival of the fittest.

Over harvesting happens when a crop has been harvested so many times that the land or crop does not have a chance to recover before the next harvest. The result is that the harvest return diminishes.

Since this is an extinct animal, we do not know a lot about the behavior of the animal. They traveled in herds of 30-50, giving some safety in numbers. Like all horse-like animals, they have hooves and teeth they can use to defend themselves, and they can run. Unfortunately, they met up with the ultimate predator- man, and were hunted to extinction.

Extinction is an intrinsic part of the evolution of new species, and is a direct consequence of the forces of natural selection. However, unlike the divergence of species (a process called speciation), one or more species can go extinct at variable rates. For example, marsupial mammals disappeared (from the larger continents)over a long period of time as they lost out to placental mammals. However, most species today disappear at alarmingly rapid rates because of the loss of their habitat.

the Quaggas adaptations were the special skins the sense and the ability to blend in with SOME places

No species has ever been threatened to extinction due to regulated hunting. In fact, it was hunters who demanded the establishment of our wildlife resource agencies and demanded they set seasons and bag limits.

When you see a thriving population of deer, bear, and many other species- thank a hunter. They brought them back from the era of over exploitation, and keep their populations in balance with the animals available habitat.

Snookums' is a pet name for your sweetheart.

Cave lions are an extinct species but we assume they reproduced in pretty much the same way as modern lions, viz by copulation between a male and a female lion resulting in the female becoming pregnant, carrying the fetus for some period of time and then giving birth to the cub via live birth.

Lipids are good for you but they need to be regulated. The main function of the lipids is to facilitate various cell activities by providing energy.

One way it has changed over time is the use of technology. People do just about everything with the use of technology?æfrom paying bills, to writing letters and doing their homework.?æ

== == Given that the definition of an "extinct" animal would be a species of which no living specimens have been sighted in years, then there are no extinct animals in the world. However, if you wish to know how many species have become extinct, I suggest you look at the Wikipedia post linked below. There you will find a list that, excluding the dinosaurs, includes thousands of extinct animals, birds, fish, reptiles, etc. Consider that well over 90% of all the life forms that ever existed on earth are extinct, a complete list would be huge.

There are many animals...pandas, tigers, whales, etc.

listen if i have to come on here and prove all of yall wrong well lets do it. you know which ones are extinct because of disease................................... schoopid

Well, sabertooth tigers are born with tiny front teeth.

Mommoths were up to a one-three story high buiding . One foot is the size of an elephant. Crazy right?

Just to name an assortment of animals in Ethiopia: wolves, lions, servals, civets, elephants, bushpigs, gazelle, antelope, ibex, kudu, dik-dik, oribi, reedbuck, wild ass, zebra, hyena, baboon, monkeys.

They would all die and we would lose the worlds largest land animal and all of the future would hate our generation.
