Why did human hand adaptations help to make humans such a successful species on earth?

Our hands are adapted for grabbing, holding and manipulating. These are three distinct functions. Most animals can grab, but they use claws, which we don't have. Some can hold things, but again they have to use their claws. We developed opposing thumbs to allow us to hold things. We developed long fingers to allow us to manipulate items that we are holding. Animals like big cats, bears, wolves, etc. do not have long fingers and have a real hard time manipulating.

How did humans become the most dominant species on Earth?
Through superior intellect.Answerwell, we were put on the earth to rule over animals also we were more smarter
What observation of species distribution across earth support the theory of common descent?
One can see similarities in organisms that are found in close proximity, but each population has adaptations that suit the organisms to their particular habitat.
Are humans destroying the earth?
Well, that's a difficult answer. Many say the earth may never recover the lost species due to human construction. Earth will replentish with new species soon enough. As long as we know that we should share the earth with the animals and plants that have been here for millions of years. We cannot control wildlife. We cannot kill off every species. But we can help ourselves by helping the earth. One step at a time.
What percent of the Earth's plant and animal species have not discovered by the scientists?
since they are not yet discovered, there is no exact percentage of plants and animals, There is an enormously large number of endangered species living in tropical rain forests, and most of these have not yet been "discovered" by scientists. Because rain forests are quickly being converted to farmland and human settlements, many of these species are becoming extinct before humans know anything about them. (it said endangered species how about the none, can you imagine how many are they) this is the other one: Because most of Earth's biodiversity (the number of species in a given habitat) is not yet discovered and cataloged, it is likely that there are perhaps several million endangered species on Earth. thanks to this site: http://www.scienceclarified.com/El-Ex/Endangered-Species.html
The largest numbers of species of organisms on the earth are currently?
The largest numbers of species of organisms on the earth are currently bacteria. They out number plants and animals by far.
How many are there of a species?
It depends on the species. If it's endangered, there could be only a few (single numbers maybe to 100's or 1000's). If it is a very successful species like humans, there are around 7 billion humans on earth.
What do the earth has?
it has species,humans,and most of all the nature
Most species on Earth today are?
humans --------------------------------------- There are far more insects than there are humans!
What would happen if there was no pioneer species?
i think that there will be no humans on earth
Are humans the worst species on earth?
That depends on your point of view.
What might humans to increase the earth's carrying capacity for all species?
because of the gravity of the earth
What might humans do to increase the earth carrying for all species?
Humans need to maintain enough space and resources to increase the earth's capacity for all species. They have to make sure that they and other people have enough to survive.
Why do alien species cause so many problems?
they hate the Earth and Humans. :(

Are humans part fish?
No, humans were formed from the dust of the Earth and were the first living creatures. Fish are a whole other species.
What is a way that humans could increase the earth's capacity for our species?
by eating only plants
Are giraffes a harm to the earth?
No, giraffes do not harm the Earth. No species in its proper ecosystem is harmful to the Earth as a whole. Rather, every species in its natural ecosystem helps to support the ecosystem. The only exception to that rule is humans.
