Darwin’s theory of evolution, yet remarkable and extremely valuable to the field of science, there were a few dilemmas that Darwin faced. ...
Darwin’s next dilemma was in blending inheritance. ... Alleles are alternate forms of a gene. ...
Darwin’s final dilemma was centered around organisms that had long been extinct. ... Darwin believed that fossilization was rare, but now we can look and see that there is a fairly accurate record of evolutionary change. ... Intermediate fossils were just being discovered in Darwin’s time. ... The simplified classification is known as the binomial system of nomenclature. ... Kingdoms are the broadest classification, being that there are only six kingdoms and the species is the representative of only one organism. Over time, the organization of classification has changed. ... Whittaker (Solomon et al 2002) proposed the five-kingdom classification, used until the late 1970s. The new classification consisted of two kingdoms, the Fungi and the Prokaryotae kingdoms. ...
DNA also affects the phenotype of organisms through gene expression. ... A phenotype is the physical or chemical expression of a given organisms’ genetics (Solomon et al 2002). There are two main parts of gene expression; Transcription and translation.
