Without heredity what use would there be to selection and why evolution? Just take beneficial mutations in the germ line for example. No heredity and nothing to enter the populations gene pool and no evolution. No heredity and there would be no variation in populations and the first environmental challenge would carry your population to extinction.

What is the necessary conditions for evolution to occur?
Variation must exist.
Which of the following is necessary for evolution to occur?
Variation must exist
In order to use the Hardy-Weinberg equation to calculate genetic variation in a population what conditions must exist in the population?
All organisms must reproduce.
For a mutation to affect evolution it must occur in?
For a mutation to affect evolution it must occur in the dominant allele. This allele is what is passed on.
What are some ways to prove evolution is wrong?
Evolution, the change in allele frequency over time in a population of organisms, is a fact. Show evidence that this does not happen. I think you would find that very difficult to show since change in allele frequency is so easy to observe. Now, to show that the theory of evolution by natural selection is wrong, you must come up with a better explanation of evolution. So far no one has done that.
What is the necessary conditions for evolution to occur?
Variation must exist.
Which of the following is necessary for evolution to occur?

What must happen first for sponges to evolve?
the evolution of cells with nuclei and organelles
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).
Should water exist?
Water must exist in order for any form of life to live on earth.
1 What conditions must exist in order for fossils to form?
erosoin
What conditions must exist in order for a force to work on an object?

These molecules must form in order for life to exist?
There are quite a few molecules that must form for life to exist. One of these life-supporting molecules is water.
