Sickle Cell Anemia: The Poster Child for Beneficial Mutation
Sickle cell disease is one of a group of disorders that affects hemoglobin. This is the molecule in red blood cells that delivers oxygen to cells throughout the body. People with this particular hemoglobinopathy (autosomal recessive) have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape that hematologist’s label drepanocytes.
Two Legacies that Changed the World
Both Darwin and Pasteur are two of the most well-known scientists of all time because they have had a profound impact in biological science leaving their imprint on the world. Charles Darwin provided us with his theory of evolution that, without question, rattled the fundamental foundations of the world’s need for a Creator.
Did the Baleen Whales Really Lose their Teeth?
In the world of Darwinian Evolution, every living creature is related. Evolutionary scientists use phylo-genetic trees that are specific types of cladograms (branching diagrams that illustrate patterns of phylogenetic relationships) to infer common ancestry among similar organisms. These family trees (or evolutionary trees) are intended to show inferred evolutionary relationships among various biological species.
DNA Can Be Made in Space
The structure of functional DNA, even in microorganisms, is so complex that even dedicated evolutionary scientists have serious doubts about the ability of the components of DNA to spontaneously form in nature via natural processes. Fred Hoyle wrote: The chance that higher life forms might have emerged in this way is comparable with the chance that ‘a tornado sweeping through a junk yard might assemble a Boeing 747 from the materials therein.’
Why Darwin Couldn’t Define the Word Species
You would think that a book entitled On the Origin of Species would have no difficulty at all defining such a central term. When you examine that publication for clarification of the word species, Darwin’s only attempt is found here: No one definition has as yet satisfied all naturalists; yet every naturalist knows vaguely what he means when he speaks of a species. Generally, the term includes the unknown element of a distinct act of creation.
