Humans had only lived not longer than a billion years on earth. But evolution is true. Its just that it takes a billion before that will happen and there are factors affecting it.
If you lived on the sea for billion of years, you and your kin will soon adopt the aquatic life and will soon have gills lol
The monkey/apes that turned into homo-sapiens lived in a place where they need to stand because of predators which they soon stand on two feet.
If you attempt to live in the sea for a billion years, your skin will become shriveled. It will take on the look and feel of puss. Then it will begin to fall off. Then you will die.
If there happened to be beneficial mutations, they are outweighed thousands of times by so many detrimental mutations, that life cannot exist through evolution. How do we know? Because we haven't found even one beneficial mutation that we know is a beneficial mutation rather than a simple built-in form of protection. However, we have identified detrimental mutations all over the place.
Evolution is a neat idea. It i s a self enclosed idea. But in real life, it is a total lie. And when the lie is perpetrated intentionally, it is a hoax. Evolution is a hoax that exists. And
that is the only way evolution exists.
Talking out of your ass again eh? Most mutations are neutral in the sense that they will not be significant. Nachman and Crowell estimate around 3 deleterious mutations out of 175 per generation in humans (2000). Of those that have significant effect, most are harmful, but the fraction which are beneficial is higher than usually though. An experiment with E. coli found that about 1 in 150 newly arising mutations and 1 in 10 functional mutations are beneficial (Perfeito et al. 2007).
The harmful mutations do not survive long, and the beneficial mutations survive much longer, so when you consider only surviving mutations, most are beneficial. Beneficial mutations are commonly observed. They are common enough to be problems in the cases of antibiotic resistance in disease-causing organisms and pesticide resistance in agricultural pests (e.g., Newcomb et al. 1997; these are not merely selection of pre-existing variation.) They can be repeatedly observed in laboratory populations (Wichman et al. 1999). Other examples include the following:
Mutations have given bacteria the ability to degrade nylon (Prijambada et al. 1995).
Plant breeders have used mutation breeding to induce mutations and select the beneficial ones (FAO/IAEA 1977).
Certain mutations in humans confer resistance to AIDS (Dean et al. 1996; Sullivan et al. 2001) or to heart disease (Long 1994; Weisgraber et al. 1983).
A mutation in humans makes bones strong (Boyden et al. 2002).
Transposons are common, especially in plants, and help to provide beneficial diversity (Moffat 2000).
In vitro mutation and selection can be used to evolve substantially improved function of RNA molecules, such as a ribozyme (Wright and Joyce 1997).
Whether a mutation is beneficial or not depends on environment. A mutation that helps the organism in one circumstance could harm it in another. When the environment changes, variations that once were counteradaptive suddenly become favored. Since environments are constantly changing, variation helps populations survive, even if some of those variations do not do as well as others. When beneficial mutations occur in a changed environment, they generally sweep through the population rapidly (Elena et al. 1996).
High mutation rates are advantageous in some environments. Hypermutable strains of Pseudomonas aeruginosa are found more commonly in the lungs of cystic fibrosis patients, where antibiotics and other stresses increase selection pressure and variability, than in patients without cystic fibrosis (Oliver et al. 2000).
Note that the existence of any beneficial mutations is a falsification of the young-earth creationism model (Morris 1985, 13).
