The presence of cytochrome P450 in all living organisms, as well as DNA and RNA are examples of this type of evidence for evolution.  

According to the Hardy-Weinberg theorem, which of the following represents the organisms possessing the dominant phenotype in a population? 

The ability to taste the bitter chemical PTC is inherited as a simple dominant trait. In a population of 1000 biology students, 640 of them are PTC tasters. What proportion of this population are non-tasters?

In a Hardy-Weinberg population with two alleles (A and a) that are in equilibrium, the frequency of allele A is 0.2.
What is the percentage of the population that is heterozygous for these allele?

Theory of origin of life was proposed by :

When environmental change occurs, multiple new niches become available. Organisms in this changing environment will undergo rapid change to fill these new niches.
This process is known as
