What is the study of how living and extinct organisms are related to one another?
The study of how living and extinct organisms are related to one another is simple. This study is called evolution.
Why did the White footed rabbit rat become extinct?
The last white footed rabbit rat was recorded at about 1845, but some were reported in 1856â??57 and maybe in the 1930s. Rats may have spread diseases or competed for food with the white footed rabbit rat.
Which event cost the dinosaurs to become extinct?
The correct answer is that no one knows.
A popular theory at the moment is that a large meteor struck the earth 65 million years ago. There is evidence of large meteor strike at a site called Chicxulub, near Mexico.
There are alternative theories such a volcanism. There are immense lava flows that date back to the time of the dinosaurs, indicating that volcanic activity was at a peak contributing to a climate change which dinosaurs could not survive.
Increased competition for resources from the growing mammal kingdom provides yet another theory.
There is evidence for all these theories, so it could just be the combined effect of all these factors that led to the dinosaurs demise.
It is a sort of cat-like mammal that lived a long time ago, and it was the very first carnivor. Sort of weasel-like. It's fur was mostly dark---wolfish colors. It hunted bugs and looked for plants---Until, that is, some of the Miacisi grew carnassials(cheek teeth) And that led to hunting small rodents and birds,etc.
No, Metalworking is fake. There are no such things as mega sharks!
Why did the passenger pigeons become excent?
The biggest reason was over hunting, but deforestation also contributed. The Passenger Pigeon was the largest species of birds, during the 1800's. It contained more individuals than all other North American birds combined. But sadly, by 1900s that powerful population had been reduced to one bird named," Martha" who died on September 1, 1914 in captivity at the Cincinnati Zoo. At one time a single flock of passenger pigeons might have more than 2 billion birds. That is just one flock, there were many flocks in the US at the time of this bird's peak of abundance. But, unregulated commercial hunting, specifically for their meat, on a wholesale scale, used those large billion bird flocks to man's advantage and it devastated the birds populations. The species migration and nesting habits also made them easy targets for large number kills, either by netting, torching, or special firearms, even one, the forerunner of the machine gun. By 1855 one year in Michigan a billion birds were, so called "harvested". The passenger pigeon's population, of course suffered a collapse under the strain, and could not recover. There were no protection measures, no conservation lands. The pigeons left were scattered across the US and that made breeding difficult and the numbers continued to decline. By 1900 all wild passenger pigeons were extinct. Now, with today's knowledge, some believe that the species should have been able to recover from the uncontrolled commercial hunting, but the scattering of the birds may have been the final straw. The large flocks may have been part of their rituals for breeding and once scattered these rituals were not triggered, therefore the breeding declined and the species suffered extinction. For more details, please see sites listed below.
The passenger pigeon went extinct because of hunters over hunting the animal and habitat loss.
What year did the toxodon become extinct?
Like many ice age species, it became extinct at the end of the Pleistocene Epoch 16,500 years ago.
Your question does not really make sence - so I'll assume you mean
"How does a swan fly?"
And the answer is - by pushing their wings up and down. In other words - flapping them.
What was the fourth major extinction event?
During the 4th Extinction, or Triassic-Jurassic extinction, 90% of all species died within just 10,000 years. The 4th Extinction was thought by many scientists to have been caused by massive volcanic activity or asteroid impacts resulting in severe climate change.
When did the Tyrannosaurus Rex became extinct?
Fossisl specimens date from about 126 million years ago, plus or minus a couple of million years. Unless and until a more recent fossil is found of Utahraptor, this should be considered the extinction limit.
How many teeth does megalodon?
Most sharks have about 3-5 rows of teeth at any time. The front set does most of the work. The first two rows are used for obtaining prey, the other rows rotate into place as they are needed. As teeth are lost, broken, or worn down, they are replaced by new teeth. Megalodon may have had hundreds of teeth at one time.
When did predator X go extinct?
nowadays many animals are became extinct because there is a change in environment so a lot of them facing crises as water sources dry up specially in Africa and water and food shortage in addition habitat loss due to forest devastating moreover poaching and pollution how menace the earth
Aurochs were found in North America and Europe; the last one dying out in Poland in the year 1627.
What caused the megalodon shark to become extinct?
Yes. Scientists believe that they died out approximately 1.5 million years ago. See the related link for a picture.
*That is the popular thinking, but there is evidence to the contrary. As well, the ceolecanth was believed to have been extinct for millions of years. Until people began catching them. There is no way to prove beyond a shadow of a doubt that they truly are extinct.*
What is the number one cause of current animal extinctions?
If you were asking for main reason for mass extinctions in general, I would say that it is abrupt climate changes.
However the K-T mass extinction was a consequence of a major comet/asteroid impact, and perhaps the Ordovician-Silurian mass extinction (the second largest mass extinction after the Permian extinction, the «Great Dying») could have been caused by a Gamma-ray burst from a supernova (or hypernova) explosion thousands of light-years distant, or could have been the outcome of the most severe glaciation of the Phanerozoic eon.
The most severe of all mass extinctions was the above mentioned Permian mass extinction, and the reasons for such a catastrophic event are not yet fully understood.
But you asked which is the main reason for the CURRENT extinctions. Indeed the scientific community believe that we are now watching a new MASS EXTINCTION, not just the extinction of a limited number of species.
I am sorry to say that I, personally, believe the reason is human beings.
And I know well this is currently a matter of debate and vigorous scientific and political dispute, due to the monstrous profits of polluter industry, along with the big bank's investments and the high finance lobbies supporting these industries.
Did woolly mammoths travel alone?
Like elephants today, the Woolly Mammoth were social animals, and the females lived in related groups or herds.
Until the male mammoth reached the age of three to four years of age, he also lived with this group of closely related females. At that age, he started exploring his world and left the group behind. For two to three years after he left the female herd, he may have lived with a nomadic band of other male like age mammoths. This was called a bachelor herd.
Males were not usually related to each other in the bachelor herd, and came and went as they chose. As the males reached the age of 20, they no longer associated with herds of either sex unless it was time to breed.
What is factors may have caused the extinction of woolly mammoth?
As the world got warmer the woolly mammoth habitat decreased their source of food and as the human population grew the more hunters their was around to hunt the mammoths so that could drove the last of the mammoths to extinction
How big were the saber tigers teeth?
Sabre-Toothed Tiger teeth were approximately 17 cm (7 inches) long. Their teeth did NOT continue to grow through their life.
The 2 types of tiger had the following sized teeth: Genus Homotherium-4 Inches Genus Smilodon-7 inches
"Smilodon" had ENORMOUS teeth! -I've seen them (the top two being the longest) as long as eight inches! The La Brea tar pits near Los Angeles, California has produced the largest collection in North America.
What features do mastodons have that were unique to its survival?
Woolly mammoths had far too many adaptations to list them all. Here are a few of the adaptations that they had:
1. Like modern elephants, they had a long trunk for grasping food.
2. Their large size would have made them difficult to hunt, even for a skilled predator.
3. Woolly mammoths had a thick layer of fur, as well as a thick layer of fat, to keep them warm in the cold tundra climate.
4. The fact that they had small ears minimized heat loss.
How big was the short face bear?
The biggest short faced bears were Agriotherium Africanum at 650 kg, Arctodus Simus at 700 - 800 kg( large males could weigh a tonne) and Arctotherium angustidens at 1000 kg, eventhough large males could get to 1500 kg.
Why did giant koalas become extinct?
Koalas as a species are a long way from extinction. There are however regional areas of Australia where traditional populations of these animals are under threat due to the usual man made problems of urban development, deforestation etc. Despite all this, the koala is holding its own and has many areas of protected habitats to live in. On an island off the southern coast for instance, there are literally too many koalas for the food sources to keep up and the solution for this still hasn't been worked out. One drastic idea put forward is to destroy a certain number of koalas so that equilibrium can be established.
Koalas are protected and have been protected for a long time. They are not found in all areas of Australia. They are being pushed out of their natural habitat by urban growth. Koalas are also dying from a disease called Chlamydia, infecting the eyes and causing blindness, and compromising the koala's fertility.
The conservation status of koalas varies from region to region in Australia, but they are by no means becoming extinct. For example, due to farming and land clearing, native koalas were eradicated from Western Australia and South Australia in the last century, but moves have been made to reestablish new colonies in both states. Currently, koalas are thriving on Kangaroo Island in SA, and in other isolated colonies throughout SA's southeast.
Koalas are still listed as "common" in most parts of Queensland, but in the southeast region of Queensland, their status has been changed to "vulnerable". The NSW Government listed the koala as "rare and vulnerable" in 1992, and following protective measures, this has been changed to "vulnerable". In Victoria, the koala is not on the threatened species list at all, and in some protected and remote regions, there is actually an overpopulationproblem.
Despite urging by conservation groups since around 1992, Australia's federal government has not yet listed the koala as vulnerable, except in certain areas. Even international conservation groups cannot agree. Meanwhile, the International Union for Conservation of Nature (IUCN) lists the koala as "potentially vulnerable", while the US Endangered Species Act lists the koala as "threatened".
