Human Embryo Development - The scientific miracles of Quran
Life is as complex as the universe, and if the last chapter provided you with a dose of spiritual experience, this chapter will supply you with another dose. The factories, inside your 100 trillion cells, will bewilder you. The length of the DNA in your body, which exceeds the distance between the Earth and the Sun, is incomprehensible. The optimal structural design of the birds′ bones attests to an Omnipotent Creator. Yet the evolutionists want to convince everyone that we have gone from hydrogen to human! In doing that, they are introducing the following definition of the hydrogen gas:
"Hydrogen as an odorless, tasteless, flammable, invisible gas which, if given enough time (say 10 billion years), becomes people!"
Again, as you read this chapter, keep asking questions: Who, Why, and How, you will have only one logical answer: "God is the Mighty Creator and He made it His Way."
What exactly is life, and how and where did it begin. Scientists’ answers to these questions are changing as discussions and theories pour in from fields as diversified as oceanography and molecular biology, geochemistry and astronomy. Did life start as organic soup in a warm pond, or under the hellish skies of a planet, unknown to us, racked by volcanic eruption and threatened by comets and asteroids. Then the intruders from outer space may have delivered the raw material necessary for life. The basic concept of evolution is that life started spontaneously, here on Earth or on an unknown planet, and took a very slow process to evolve from atoms to amino acids to proteins, to cells, to fish, to amphibian, to reptile, to mammal, and finally to human. This idea is very similar to some monster like Frankenstein, pieced together from different dead elements and jolted into life by lightening bolts.
Proteins are the building blocks of living organisms. They make up much of the structure of all life forms. At the atomic level, a protein molecule consists almost entirely of a handful of elements - hydrogen, nitrogen, oxygen, phosphorus, sulfur, and most importantly carbon. Because carbon easily forms multiple bonds with as many as four other atoms at once, it acts as a kind of glue cementing together the pieces of life’s complex molecules. The reason that carbon bonds so easily is that it has relatively few electrons. In a carbon atom, electrons orbit a nucleus in what may be thought as concentric shells. In all atoms, each shell may hold certain number of electrons. The inner shell accommodates as many as two, while the next one can hold eight electrons. But a carbon atom has only six electrons; two electrons in the inner shell and four in the next, leaving four vacancies in the outer shell.
Proteins are large complex organic compounds, made up of twenty different kinds of smaller compounds called amino acids. Large protein molecule consists of hundreds of thousands of amino acids. One protein differs from another in its number, sequence, kind, and arrangement of amino acids. A peptide is a two or more amino acids kept together by a chemical bond called the peptide bond. Hair and fingernails are proteins that differ because of amino acids. Hemoglobin is a blood protein made of 4 chains of amino acids. The twenty different kinds of the amino acids can form an almost endless number of proteins, 2.5E18 or 2.5 billion billion. It is estimated that the number of kinds of proteins in a human body ranges from 10,000 to 50,000.
It is hard to imagine that a human being starts as one single fertilized egg. It grows and develops inside its mother until birth. At birth, a baby is made up of over 60 trillion cells. As early as 1900, scientists knew that chromosomes were located inside the nucleus of a cell. They also knew that chromosomes carried hereditary information in complex molecule called DNA, short for deoxyribonucleic acid. DNA is named for the sugar deoxyribose, which it contains. However, the structure of the DNA was not known until 1953, when scientists suggested a model for DNA. That model looks like a twisted ladder with rungs, made up of four nitrogen bases. One molecule of DNA may contain 20,000 pairs of these bases.
When a cell is divided and replicates itself, by a process called mitosis, the DNA molecule must also make exact copies of them. First, the DNA molecule comes apart like a zipper being unzipped. The two halves of the DNA separate between the base pairs. Then new bases, from the contents of the nucleus, attach to each half like puzzle pieces. Thus two identical DNA molecules are formed. Like a biological librarian, DNA preserves the information needed to fashion the protein molecules. A similar compound called RNA, short for ribonucleic acid, helps turn these instructions into reality. No evolutionist can be sure how or when DNA and RNA first emerged on Earth. The key to the DNA-RNA partnership is a shared language, spelled out along the DNA strands in three-letter "words" called codons. A codon is made up of the bases of three successive DNA nucleotides. The most common codons simply specify a particular amino acid.
If codons are words, genes are the sentences they form, beginning with a special initiator codon and ending with a terminator. A gene’s message consists of a list of required amino acids, arranged in an order needed to make a particular protein. DNA’s genetic messages are readily duplicated by messenger RNA, a molecule that effectively assembles itself during the copying process. Incorporating DNA’s instructions in its own structure, the messenger RNA then travels out to the machinery of the outer cell, where it begins the manufacturing of a specific protein molecule by following the recipe it carries.
To translate genetic information into proteins, living organisms follow a complex manufacturing process. Work begins as a strand of messenger RNA enters the cell’s protein assembly area, carrying a genetic code for a particular protein. The messenger RNA goes on its way through the watery interior of the cell in search of a structure called the ribosome. Typically a millionth of an inch across, these sophisticated protein assembly machines are equipped both to read the messenger RNA’s orders and to carry them out.
Once the messenger RNA docks at a given ribosome, the ribosome looks for the beginning of the RNA message, then attaches there. Messenger RNA proceeds to wiggle through the ribosome, allowing it to read the RNA codons in sequence. For each codon, the ribosome chemically signals to the transfer RNA, a type of RNA, whose job is to deliver a single amino acid. When the transfer RNA arrives, carrying the required amino acid, it touches down just long enough to unload its amino acid. Then, the ribosome links the incoming amino acid to a growing peptide chain. This process is remarkably efficient even in a bacterium; one ribosome can attach twenty separate amino acids to a peptide chain every second!
After the final codon has been read and its message obeyed, the ribosome releases a finished peptide chain into the cell. The peptide’s electrochemical properties will quickly wrap it and other peptides into the folded arrangement that forms a particular protein molecule. The molecule’s work will depend on its identity: the protein known as collagen provides structural support in bone and ligaments, for example, while proteins called antibodies fight disease.
Assuming that all of the above was self-developed without the Hand of a Mighty Creator is analogous to believing that a monkey randomly throwing pieces of brick, iron, wood, and glass over a long span of time to make a magnificent high-rise building!
It is extremely hard to believe that a biology teacher explaining the above process without getting excited. This is not a simple process. Yet, this is a simple proof that God exists, and He is the Only One that can design this process.
Would you do yourself a favor? Read the above process again, and ask yourself who directed this step? It is inconceivable that nature could organize this process with such detail and efficiency.
