Which is more likely to be true natural selection or evolution?
Evolution, of course. Evolution can happen without natural selection in some cases; drift, flow. Generally though, natural selection causes evolution and then, by definition, would come first.
How does natrual selection happen?
Natural Selection is the process of organisms adapting and evolving with their surroundings. The weaker ones who cannot adapt die off while the adapting ones stay alive.
What makes natural selection happen?
Natural selection happens when individuals with traits that are better adapted to their environment are more likely to survive and reproduce, passing those advantageous traits on to their offspring. Over time, this process leads to the accumulation of beneficial traits in a population, increasing its fitness and ultimately driving the evolution of a species.
How does selection in natural selection works?
Some individual organisms are better equipped to live and reproduce in their environment than others. If what makes them better equipped is heritable, their offspring will be more numerous and will tend to inherit the same traits or qualities themselves. The opposite will happen to those poorly equipped. They will have fewer or no offspring, and their negative traits will tend to disappear from the population as time goes on. These two tendencies are called positive (natural) selection and negative (natural) selection respectively. Natural selection is always relative to the environment. What is advantageous in one environment may not be so in another, and what is disadvantageous (deleterious) in one environment may not be so in another.
Describe how natural selection is related to organic evolution?
Natural selection is a key mechanism driving organic evolution. It is the process by which organisms with advantageous traits for survival and reproduction are more likely to pass those traits on to future generations, increasing their frequency in a population over time. This results in the evolution of populations as they adapt to their environments through the accumulation of beneficial traits.
Is descent with modification caused by natural selection?
No, it's the other way around: descent with modification is what you need for natural selection to happen.

What happen to an individual that is poorly suited to its environment?
They die. This is called Natural Selection.
What happen that made Helen Keller died?
Natural causes.
In order for evolution by natural selection to occur what has to happen?
There must be genetic variation, the variation must be heritable, and there must be differential reproduction (due to competition).
How does natrual selection happen?
Natural Selection is the process of organisms adapting and evolving with their surroundings. The weaker ones who cannot adapt die off while the adapting ones stay alive.
Where are humans going?
Nowhere predictable. Natural selection reacts to things that happen; there is no plan to it. Humans are not developing along any lines.
What causes build up of nitrogen in joints and what is the cure?
It is a natural part of the gasses that happen in joints it is not a problem.
Why is time an important factor in the process evolution by natural selection?
Because natural selection only preserves incremental beneficial traits to the organism and many different areas of the organism are undergoing mutation and natural selection at the same time against the backdrop of the immediate environment. If a population of organisms, subject to allele change due to natural selection, is not in a changing environment, or split in a allopatric event, then adaptive change will be very slow, or will not happen at all and selection will winnow those variants and stabilizing selection is taking place. Regression to the mean of phenotype.
When did Hudson Selection happen?
Hudson Selection happened in 2003.
When did Stepping Selection happen?
Stepping Selection happened in 2000.
