Life's Greatest Miracle: Personal Reactions and Observations Essay

This essay delves into personal reactions and observations regarding life's greatest miracle, the creation of a new baby. It highlights the complexities of human reproduction, contrasting it with other methods like bacterial cloning. The essay discusses the role of genes in determining traits and the intricate process of cell development and organ formation. It also touches upon the challenges faced by sperm in fertilization and the significance of chemical messages in guiding embryonic development. The author reflects on the unique human experience of childbirth and the privilege of witnessing this miracle. The essay references NOVA PBS's documentary on the subject, providing a scientific perspective on the biological processes involved in creating new life.

Life’s Greatest Miracle: Personal reactions and observations
People do all sort of things to get attention. The human body is well structured and
formed for reproduction. Knowingly and sometimes unaware, both males and females prepare
for reproduction in different ways. It is observed that globally 365,000 new babies are born daily.
A baby starts from a single cell which creates trillions of cells as it develops. Cells produce
tissues and organs that allow different functions with the brain at the center of it. The video
uncovers life’s greatest miracle, i.e., the creation of a new baby.
Most living things are well designed and adapted according to their method of
reproduction. If humans were to reproduce like bacterium do, which is by cloning where the
DNA produces exact copies of itself, then human life would be in great danger because one
successful parasite could wipe all the humans from the face of the earth.
When young parents are expecting a baby, the baby will come carrying the same genes
from both the father and the mother. These genes are unique but will include genetic information
that is a combination of all their ancestors. Females produce ovum when they are young as
opposed to males who are able to produce sperms only after puberty. The ovum will keep dying
and at a certain age according to the video, at age 31, there will be only a few thousands eggs
remaining in a woman’s ovaries. However, quality precedes quantity, and they can still be
fertilized to make a new baby.
It is observed that in a healthy man, 60% of the sperms might not be able to swim
towards the fallopian tube to fertilize the ovum. The sperms will have to face challenges before
they can be able to reach the ovum and create a viable embryo. The genes help the cells develop

organs with the use of DNA. Cells use chemical messages to know where they are supposed to
be and what they are supposed to do, for instance, create an eye. Molecules, turn cells on to
produce proteins which build organs. DNA determine the genetic composition of the new born
with half coming from females and the other half coming from males.
The power of genes, to create a boy or a girl child by using cascades of chemical
reactions, defining the form and functions of all the cells in the body. Billions of chemical
messages are sent throughout the development of the embryo all with different meanings and
interpretations. After two months all organs are developed, and the fetus is ready. It grows
through a constant supply of nutrients and in the next six and half months the fetus prepares for
birth.
Finally, because of the complications and pain that come with the giving birth in humans,
humans are the only mammals that give birth in the presence of others. Those present when
giving birth have the privilege of witnessing these life’s greatest miracle.
