Discussion 1: Evolution Briefly describe Darwin's theory of natural selection and discuss how this theory differs from
amarck's ideas about evolution. Why does Darwin's theory work while Lamarck's does not?
What do you think is the difference between science and religion in describing humans' place
in the worldDoes it make a difference for humans if we evolved versus if we were created? In
what ways?

Population Variability

Deriving Genotypic and Allelic Frequencies

Hardy-Weinberg Equilibrium

Evolutionary Genetics

Darwin's Theory of Natural Selection

Darwin's Theory of Evolution by Natural Selection

More individuals are produced each generation that can survive.

Phenotypic variation exists among individuals and the variation is heritable.

Those individuals with heritable traits better suited to the environment will survive.

When reproductive isolation occurs new species will form.

These are the basic tenets of evolution by natural selection as defined by Darwin. The following is a quote from Darwin.

"Variation is a feature of natural populations and every population produces more progeny than its environment can manage. The consequences of this overproduction is that those individuals with the best genetic fitness for the environment will produce offspring that can more successfully compete in that environment. Thus the subsequent generation will have a higher representation of these offspring and the population will have evolved.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
