Are bats the only mammals capable of active and sustained flight
Bats are the only mammals capable of true flight. They belong to the Order Chiroptera, which means "winged hand". Although often mistaken for rodents, they are more closely related to primates.
What was the theory of natural selection proposed by Charles Darwin almost 150 years ago
The theory of natural selection, proposed by Charles Darwin almost 150 years ago, hypothesizes that organisms with traits that give them a survival advantage tend to live longer and produce more offspring. Over many thousands of years of evolution, those beneficial characteristics dominate the gene pool.

Are big trees incredibly important ecologically reading answers
Explanation: Big trees are incredibly important ecologically. For a start, they sustain countless other species. They provide shelter for many animals, and their trunks and branches can become gardens, hung with green ferns, orchids and bromeliads, coated with mosses and draped with vines.
What is the only mammal that can truly fly
Bats
Bats are the only mammals that actually fly, flapping their wings to propel them in flight. Some mammals, such as flying squirrels, only glide rather than fly. Because bats are unique they are classified in their own special order of mammals, called Chiroptera.
What is the only mammal on earth that can actively fly
Bats are mammals of the order Chiroptera (/kˈaɪrəptɛrə/). With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight.
What did Charles Darwin discover in 1859
1859: Darwin Published On the Origin of Species, Proposing Continual Evolution of Species. The first printing of Charles Darwin's book, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, sold out in a matter of days.
What is 1 Darwin’s theory of natural selection
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
Why do we protect polar bears
Importance of polar bears. Polar bears are at the top of the food chain and have an important role in the overall health of the marine environment. Over thousands of years, polar bears have also been an important part of the cultures and economies of Arctic peoples.
Why do whales leave the ocean and become stuck on beaches
If one member of the group is sick or in trouble, its distress calls can cause the other members to follow it to the beach, resulting in a mass stranding. Orcas sometimes intentionally beach themselves to hunt for shoreline seals. They then wait for waves to help get back to sea.
What animal can fly the longest name
the soldier fly
The longest scientific binomial name given to any animal is Parastratiosphecomyia stratiosphecomyioides (containing 42 letters), which is a species of stratiomyid fly with a metallic green thorax and abdomen, known as the soldier fly.
What mammal can’t jump
Elephants
Elephants can run up to 25 miles per hour. However, they remain the only mammal on earth that can't jump. They always keep one leg on the ground – even when running.
When did life first evolve on Earth
about 3.7 billion years old
With an environment devoid of oxygen and high in methane, for much of its history Earth would not have been a welcoming place for animals. The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old.
What was still a mystery to Darwin
What is the abominable mystery Darwin coined the phrase, abominable mystery, in 1879. In a letter to his closest friend, botanist and explorer Dr Joseph Hooker, he wrote: "The rapid development as far as we can judge of all the higher plants within recent geological times is an abominable mystery."
Is there a natural selection 1
The game was created by Charlie "Flayra" Cleveland, who later founded the company Unknown Worlds Entertainment. Natural Selection v1 was first publicly released on Halloween 2002, and is now at version 3.2. Natural Selection 2 was released in late 2012.
What is a real life example of Darwin’s theory of evolution
Consider the giraffe, for example. A Darwinian theory of evolution posits that it was through random variation that some giraffes had longer necks than others. Thanks to their long necks, they were able to reach leaves high up in the trees in their environment.
What will happen if we don’t save polar bears
Polar bears are a critical part of the Arctic food chain, keeping both the seal and fish populations in check. Without these top predators, the Arctic ecosystem would be thrown out of balance—possibly change permanently.
Can we really save the polar bears
We can all contribute to reducing climate change, and therefore help polar bears and other endangered species. A significant cause of climate change is the emission of polluting gases from burning fossil fuels, such as coal and oil. Fossil fuels are burned when we use electricity or drive our cars, among other things.
Can you save a beached whale
The good news is that some of these whales do survive. If you spot a beached whale, call the local authorities immediately. Do not attempt to approach the whale on your own—you never know when that powerful tail will decide to thrash, or if they might carry diseases. Let the trained professionals lead the rescue.
Can beached whales survive
Despite breathing oxygen like land mammals, whales were born to be in the ocean, which makes Cetacean stranding such a problem. Cetacean stranding often leads to death due to dehydration. Whales have an incredibly thick layer of insulating blubber.
Is the world largest bird but Cannot fly
Ostrich. The mighty ostrich is truly the king of birds. The largest living bird, ostriches can grow up to 9 feet tall and weigh more than 300 pounds. Their eggs, fittingly, are also the world's largest—about 5 inches in diameter and 3 pounds in weight.
Which animal is king of flying
The eagle is called the "King of Birds", but this title has also been given to the Philippine Eagle.
What mammal can fly but can’t fly
6. Bats are the only flying mammal. While the flying squirrel can only glide for short distances, bats are true fliers. A bat's wing resembles a modified human hand — imagine the skin between your fingers larger, thinner and stretched.
Which organism has 3 hearts
Octopuses
Octopuses and squids (animals called cephalopods) have three hearts. Two hearts pump blood to the gills to take up oxygen, and the other pumps blood around the body (Figure 1). Worms are also unusual, with five structures called aortic arches acting as basic hearts.
How did Earth look like 4.5 billion years ago
Once upon a time, about 4.5 billion years ago, the Earth was an unformed doughnut of molten rock called a synestia — and the moon was hidden in the filling. That's one possible explanation for the moon's formation, anyway. And according to a new paper published today (Feb.
Who was the first human on Earth
Homo sapiens, the first modern humans, evolved from their early hominid predecessors between 200,000 and 300,000 years ago. They developed a capacity for language about 50,000 years ago. The first modern humans began moving outside of Africa starting about 70,000-100,000 years ago.
