Because we're unique and competely different from other living things.
Yes, the earth is the only planet where humans live. The probability of finding the exact same species living on another plant is zero.
Currently now there is but during the days of the caveman there was seven more species of human but in the end we were the more advanced in brains
Tricky question... Scientists have described and given scientific names to about 920,000 species of insects in the world, which is impressive since mammals (of which humans are one) only have approximately 4,000 known species. As for your actual question... It is estimated that there are 20-30 million species of insects on the earth at present. In a good year, taxonomists throughout the world describe and name about 2,000 species of insects.
Humans have a two lungs-one heart system because that is essential to survive and thrive on earth. This is the product of millions of years of evolution and humans have been molded specifically for life on earth.
No one really knows; it's a bit like the fact that no one really knows exactly when humans appeared on Earth.
Insects outnumber humans by far more than 100 million to one. There are well over one million species of insects that have been cataloged.
the only one i can think of at the moment is the eagle.
rhinoceros
As a family of animals: Insects. As one species of animals: Humans.
There is only one species of domestic cattle, however humans have produced many breeds from that species.
earth is the first planet humans have visited and the only one
Our species have been on Earth for only a couple of hundred thousand of years. The humans came about 65 million years after the dinosaurs and they went extinct after existing for about 200 million years so the human race come certainly to an end too. When no one is totally sure. But eventually every one of Earth's species will die out.
The only planet walked on by people (humans) is the Earth. The only other astronomic body that humans have walked on , is our natural satellite the Moon.
There is only one species of primate that has no pigment in its palm. This species is humans. The only other primate that has no pigment in its palm would be an albino.
There are two meanings of the word "hominid".One definition is "a member of the family Hominidae". That includes species in the genera Homo, Pan, Gorilla, and Pongo (humans, chimps and bonobos, gorillas, and orangutans).By the other definition (Homo sapiens, and species more closely related to it than to the genus Pan), the only hominids still alive on Earth are humans.
The dinosaurs are one of the species that has disappeared from the earth.
The four major species of humans are Homo sapiens (modern humans), Homo neanderthalensis (Neanderthals), Homo erectus, and Homo habilis. These species evolved and existed at different points in time, with Homo sapiens being the only surviving species.
Earth. It is the only one with the right temperature, oxygen and water.
No one knows what humans will look when they become a new species. It will depend on the type of species that humans evolve into that will determine what they look like.
