Lederberg's replica experiment explains Darwin's theory of evolution by natural selection. The experiment showed that some bacteria had mutations for antibiotic resistance before being exposed to the antibiotic, not as a result of it. This means that the mutations were random and not directed by the environment. The resistant bacteria had a survival advantage and were secreted by antibiotic. This is consistent with Darwin's idea that inherited variations that increases fitness.

The best description of natural selection is
1 The reproductive success of the members of a population best adapted to environment
2 It acts when the resources are unlimited
3 A change in the proportion of variations within a population
4 It follows Hardy-Weinberg principle
Explanation:
In the process of natural selection and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. - Natural selection is the reproductive success of the members of a population best adopted to the environment. Natural selection can lead to speciation.

Darwinism explains all the following except
1 Within each species, there are variations
2 Organisms tend to produce more number of offspring that can survive
3 Offspring with better traits that overcome competition are best suited for the environment
4 Variations are inherited from parents to offspring through genes
Explanation:
The Darwinism is lack of knowledge of heredity. Darwin's theory could not explain in the inheritance of variation from parent to off spring. The concept of genes and their inheritance was developed later by scientists such as a Gregor Mendal. So that, Darwin's does not directly address the mechanism of inheritance through genes.

Jean-Baptiste Lamarck explained evolution based on
1 Natural selection
2 Survival of the fittest
3 Mutations
4 Inheritance of acquired characteristics
Explanation:
Jean Baptiste Lamarck (1747-1829) is one of the best-known early evolutions unlike Darwin, Lamarck believed that living things evolved in a continuously upward direction, from deal matter, through simple to more complex forms, toward human 'Perfection' species didn't die out in estimations, he claimed.

Coverstone of theory of Darwin was
1 Natural selection
2 Inheritance of acquired characters
3 Omnis cellulae-e-cellula
4 Higher productivity
Explanation:
The coverstone of theory of Darwin was natural selection. This Theory was put forward by Charles Darwin (1859) in his book origin of species. The theory of natural selection is an important theory for explaining the process of organic evolution and also explained origin of species through hybridization process.
