Author's Note: The final draft of the human genome - the “book of life” has been completed. In 2000 the first draft of
the Human Genome Project was made public by the US-UK Human Genome Project’s
head, Francis Collins, and J. Craig Venter of Celera Genomics, a private
company. They led the celebration of the
most important discovery equaled only by the splitting of the atom in the last
century. The breakthrough revolutionizes medicine and biology, and has deep
ethical and moral implications, as the discovery could lead to the cure of
killer diseases through what scientists call gene therapy, and the broadening
of genetic engineering possibilities that may lead to the “creation” of life
itself.
-------------------------------------------------------------------------------------
While the
world celebrates the greatest discovery of the new millenium - the cracking of
the genetic code - let us turn our thoughts to our own biologists and dedicate
this article to them. May their
pioneering spirit in the development of biology in the Philippines be
brought closer to our youth for them to look into the great potentials of
biology as a career.
One of
the early biologists was Eduardo
Quisumbing the author of Medicinal Plants of the Philippines.
Although it was written in the fifties the book is still the most popular
reference in pharmacology. It is used in agronomy and horticulture. If you want
to know what a certain plant can cure, how it is prepared and administered to
the patient, flip the pages his book. It gives the botanical description of
the plant so that it can be identifies.
It is dubbed as the “bible of medicinal plants,” which anyone can use - in the school, barangay and in the home.
------------------------------------------------------------------------------
Nemesio Mendiola (1890-1983) is the country's counterpart of the American "plant wizzard," Luther Burbank. He was responsible in breeding high yielding rice, corn, sugar cane, and a host of horticultural crops, including fancy plants. Have you seen kamote (sweet potato) varieties with yellow, violet and blue tubers? He bred the spineless kenaf from the wild thorny native variety and became the source of fiber for commercial jute sacks.

People’s Health
and Welfare
Earlier, Leon Ma. Guerrero
(1853-1935), the father of botany in the Philippines and one of the first
Filipino pharmacists, formulated medicine and drugs from 174 plants in place of
synthetic drugs which were not available then. When President Emilio Aguinaldo
ran out of ammunition, he formulated an explosive derived from plants. It proved to be a good substitute to
gunpowder. It was later named Guerrero Powder. One of the
ingredients the author discovered is the hard seed coat of cashew (Canarium luzonicum).
“Necessity,” it is said, “is the mother of invention.” Life went through
difficult times even after gaining our independence from Spain and the US and later from the Japanese. It
is in these times that great minds were challenged.
Take the
case of Maria Y Orosa (1893- 1945).
Her discoveries in food preservation and innovations in salting, marinating,
and picklingmade home economics and food technology household terms. So
simple are her techniques that they can be adopted at the grassroots. They are also friendly to health and the
environment.
A
significant contribution to the improvement of health came from Hilarion
Lara (1994-1987), an epidiomologist who advocated environmental sanitation
in the control of cholera, typhoid, measles, dysentery and diphtheria. For this he did not only earn the title of
National Scientist, but his fame
gained international acclaim.
Beri-beri and
Allergy
It was Manuel Ma. Guerrero (1877-1919) who
succeeded in controlling infantile beri-beri.
Dr. Juan Salcedo (1904-1988)
who was then chairman of the National Science Development Board came up with a
special vitamin against beri-beri for all ages, a feat which became
internationally famous. Thanks to Dr. Guerrero and Dr. Salcedo this scourge of
millions of children all over the world can be now controlled down to the
village level. These great Filipino
scientists are dubbed the “nemesis of beri-beri”.
More
discoveries that improved health were made. Alfredo Santos (1900-1979), one of the founders of the National
Academy of Science discovered paheantharine
from plants as a treatment of high blood pressure. For this he earned the honor of National
Scientist.
Candido M. Africa (1895-1945) succeeded
in determining the causes of heart failure and how it can be prevented. In the
field of allergy, Arturo B. Rotor (1908-1993), who was also
Executive Secretary of President Manuel L. Quezon, and later President Sergio
Osmena, developed a technique in detecting and controlling allergy. It was later named Rotor Syndrome, and is
now a standard procedure used by medical schools and hospitals here and abroad.
Dr. Rotor also wrote a column, “Confidentially Yours, Doctor,” written in
simple and plain English for people to understand the doctor’s lingo. A number
of orchids he discovered were named after him.
Antonio Ejercito spearheaded malaria
control, while Dr. Sixto A. Francisco (1890-1959) fought
tuberculosis with a method he developed with the use of BCG vaccine. Anastacia Giron Tupas (1890-1972)
upgraded the nursing profession. She is
our own Florence Nightingale, the founder of the nursing profession. Fe del
Mundo (1907- ) institutionalized the
treatment of children by putting up of hospitals for children. These hospitals
are among the best-managed hospitals today. Among her inventions are an
incubator for babies, and a devise in relieving jaundice. Her name is an
institution in the field of pediatrics medicine.
Biology and
Agriculture
The
author had the privilege to study genetics under Nemesio Mendiola (1890-1983). Dr. Mendiola is the country’s
counterpart of the American “plant wizzard,” Luther Burbank. He was responsible
in breeding high yielding rice, corn, sugar cane, and a host of horticultural
crops, including fancy plants. Have you seen kamote (sweet potato) varieties with yellow, violet and blue
tubers? If you happen to see a dwarf gumamela (Hibiscus rosasinensis) with bright long-lived flowers, it is also
the work of Dr. Mendiola. He bred the spineless kenaf from the wild thorny native variety and became the source of
fiber for commercial jute sacks.
Another
great mind biology is Deogracias
Villadolid. He was professor in
zoology and served as critic of the author’s masteral thesis in freshwater
ecology. Dr. Deogracias Villadolid, a marine and fresh water biologist, is best
remembered for introducing tilapia (Tilapia
monzambica and T. nilotica) into
the Philippines
in the fifties. The fish became adapted to local conditions that today it is
the most popular fish, surpassing bangus, our national fish.
Here is a
list of other Filipino biologists and their significant contributions:
- Julian A. Banzon (1908-1988) developed
alternative fuel from coconut and sugarcane. Ironically while millions of
cars run on alcogas in other countries, we have not tapped Dr. Banzon’s
formula for our local cars.
- Felix D. Maramba Sr (1898- 1990?)
harnessed biogas from animal waste. His project, Maya Farms in Rizal, is
the most popular model in the country for small and medium size biogas
generator. Like LPG, the gas collected and processed from piggery waste is
used for the kitchen and in generating electricity. It became a world’s model for its kind.
- Angel S. Arguelles (1888-1988?) developed
fertilizers and pesticides to increase plant yield. These alternative farm inputs can save
the country of precious dollars that is otherwise spent on imported farm
chemicals, which by the way, are deleterious to health and the
environment. His formulations set the foundation of organic farming.
- Gregorio Velasquez is the father of
phycology, the study of algae, which include the seaweeds. Today the
culture of certain seaweeds, like Eucheuma
and Gracillaria and Caulerpa, constitute a multi-million
industry. Seaweeds are used as food
and raw materials in medicine and industries. Micro-algae like Spirulina and Chlorella are among today’s growing health food.
- Gerardo Ocfemia, the father of plant
pathology in the Philippines. He is best known for discovering the
cause of cadang-cadang, a
pandemic viral disease of coconut. He was responsible in the
identification and control of many other plant diseases in the Philippines.
- Dioscoro L. Umali (1922-1992) The author
had the privilege of consulting Dr. Umali for his advice in the drafting
of the Magna Carta for Small Farmers.
A former dean of then UP College of Agriculture, he assumed one of the
highest posts occupied by a Filipino in the UN as regional head of the
Food and Agriculture Organization (FAO) for Asia and Pacific. His works in
plant breeding, education and research won him the National Scientist
award.
These
scientists also excelled in their fields: Salvador
M. Africa (chemist, made glass from sugarcane bagasse), and Anacleto del Rosario (discovered
natural mineral water).
Of
course, we recognize the greatest Filipino who ever lived, the hero of our
race, Dr. Jose P. Rizal. Dr. Rizal was a biologist, agriculturist and
wildlife conservationist, even while he
was in exile at Dapitan. Among his discoveries is a winged tree lizard, which
was later named after him, Draco rizali.

The author
also expresses his admiration to these contemporary Filipino scientists whom he
had the chance to study and work with in the academe, in research institutions
and in the field. Together with other scientists, they belong to the
“contemporary school of biology.” Among them are Reynaldo A. Tabbada (botany),
Paciente Cordero (marine biology), Romualdo M. del Rosario (Botany), Ruben
Umaly (Genetics), Crisanto EscaƱo (agriculture), Carmen Kanapi (Genetics),
Sister Mamerta R. Rocero (ethnobotany), Alice Claustro (Botany), Anselmo S.
Cabigan (Biology), Irineo Dogma (Microbiology) and Lydia Joson (microbiology). The author
likewise expresses recognition to scientists in the other fields of natural
science, particularly in chemistry and physics.
The
author also acknowledges his former students who became practicing biologists -
researchers, teachers, community workers, and the like. They are among those
who constitute today’s “workforce in biology.”
New Fields of
Biology- A Challenge to the youth
These ten
major biological research areas pose a challenge to the youth of today who may
take interest in becoming biologists.
- Biotechnology
- Marine biology
- Climatology
- Human longevity
- Effects of pollution
- Endangered ecosystems and species
- Exobiology and Space biology
- Natural food and medicine
- Pandemic human diseases
- Gene therapy
Now that
the genetic code has been broken, we are embarking into new fields of science
and technology heretofore unknown to man - and into the mystery of life itself,
a subject that has long defied man’s knowledge.
The mapping of the 46 chromosomes of the human species and the 50,000 or so genes
that they hold may have taken us a leap forward into knowing the key to life.
But even if we shall have finally identified the specific role of each gene in
relation to health, behavior and intrinsic qualities, we would still be in
quandary whether this discovery will make life any better, happier and well-lived.
As we
look back, our pioneer biologists may not have cracked the gene, but definitely
they have in their own quiet and humble ways brought honors to their race and
profession. Most important of all, they
have improved the lives of millions of not only Filipinos but other people
around the world through their genius, efforts, dedication – and selflessness.
May this
article serve as a simple expression of our respect and gratitude to these scientists and
many other great Filipinos. ~
