What is man? Manuel Alfonseca

Summary: What is man?
Manuel Alfonseca
Since a little over one century, after the consolidation of evolutionist theories, and getting from them
philosophical consequences without a scientific basis, many biologists assert that man is an animal like
any other, one between millions of species of living beings, being impossible to set criteria that help us
decide if one species is more advanced or more important than any other.
Is this true? I think it evident that those criteria do exist, that we should not be denied the ability to
compare and judge, two capabilities that have made all our technological advances possible. I'll mention
just two of those criteria:
· The origin of life, about 4000 million years ago, did not have an immediately observable impact on
the physical aspect of the earth. A few changes in the water hue, or the apparition of reefs of
cyanobacteria. Nonetheless, the action of life on Earth continued slowly, culminating about 1000
million years ago in a new composition of the atmosphere with 20 percent oxygen, making
respiration possible.
With multi-cellular living beings, the physical appearance of the Earth changed deeply: the dominant
color of continents became green. Of the three kingdoms at this level of life, plant produced the
largest impact: fungi and animals are practically imperceptible from outer space.
In the last centuries, the situation has changed: for good or evil, the human species by itself has
modified the appearance of our planet. The surface of the tropical forests is getting less; a large
proportion of living species are in danger; holes in the ozonosphere turn up; the night sky is full of
