What else can I help you with?
The belief that life is a competitive struggle in which only the fittest survive?
To pit it in a more accurate form; the theory of evolution by natural selection. Not a belief, a theory in the scientific sense.
Energy source of most life on earth?
Most life on earth, gets there energy source from the sun, that is assuming that the majority of life on earth are autotrophs (plants). They get this energy by photosynthesising and getting a energy source called glucose, which is used in nearly all organisms on earth... they can then use glucose as a respiratory substrate, for respiration... Hope this helps :)
What is a part of macro-evolution?
Micro-evolution is not only a part of macro-evolution, it is the same mechanism as macro-evolution. Macro-evolution includes speciation, as a result of continuing micro-evolution.
How does evolution affect human race?
We cannot be sure of that because evolution has never been observed. And since it is a theory, it cannot be proven, even though plenty of evidence exists that it does occur. In addition, since it is so difficult to observe happing in real life, instead of just fossils, its affect on us humans is very hard to measure or even speculate. One area where there is a hint of what the effect of evolution may be can be observed in bacteria. Though they do not actually evolve into a new species, we can see them change in how they adapt to antibiotics. Some strains of staph, or staphylococcus, have grown so resistant that they have become a danger to us because we cannot use antibiotics to stop them. At the other end of the scale we have the example of the cockroaches. They are so superbly evolved to survive that they have hardly changed at all in millions of years. It has been said that if we ever have a nuclear war, they may be the only living animals left because they can live in high levels of radiation. So maybe the answer to what impact evolution has on us today is that there are animals that may actually survive better than can.
What is the only taxonomic category that exists as a discrete unit in nature?
Species
Water exists on other planets in the solar system. Life exists only on Earth because water exists as a on Earth.?
The word you're missing is.... liquid.

What is a cure for evolution?
One word: extinction. As long as life exists, organisms will reproduce with variation - which means per definition that evolution will occur. The only way for evolution to stop happening is for life to cease existing.
Is earth only planet that has nature?
No. Nature exists on and in every planet. Earth is, however, the only planet in our solar system to have life.
Does Neptune have grass?
No. There is no life on Neptune. Neptune is too cold to sustain any sort of life that is found on Earth and it does not have a solid surface. Grass only exists on Earth.
What does the fossil record show about evolution of life?
Get Justin bieber tuckets bum :) Evolution does not make any regard to the origin of the earth. It only deals with the development of existing life.
What unique about planet earth?
What is unique is that it has beings who ask questions starting, 'what is unique about . . . ?'
When was the earth created according to evolution?
Evolution does not make any regard to the origin of the earth. It only deals with the development of existing life. Geological and physical sciences teach that Earth formed approximately 4.54 billion years ago.
Where is life known for certain to exist?
Life is known for certain to exist on Earth. While there are potential signs of past life on Mars and potential for life elsewhere in the universe, Earth is the only confirmed location where life currently exists.
Where did evolution occur?
Evolution has occurred all over the world, in various environments and ecosystems. It is a continuous process that has shaped the diversity of life on Earth over millions of years. From the oceans to the mountains, from tropical rainforests to polar regions, evolution has left its mark everywhere.
What is only the planet earth found with?
The presence of liquid water on its surface. Earth is the only known planet in our solar system and, so far, in the universe where water exists in liquid form, a key ingredient for supporting life as we know it.
Are there any other planets that sustain life?
So far, earth is the only planet known to support life, but many scientists thing that life probably exists on other planets.
