Cheers for the Maligned Goat

I have a confession: I used to look down at the piddling goat. It is too weak to pull a plough or give milk in abundance like the cow. It cannot serve as a beast of burden like the lowly donkey, the transporter par excellence for farmers and armies up till World War II. It … Continue reading “Cheers for the Maligned Goat”

I have a confession: I used to look down at the piddling goat. It is too weak to pull a plough or give milk in abundance like the cow. It cannot serve as a beast of burden like the lowly donkey, the transporter par excellence for farmers and armies up till World War II. It is too small to give people a ride, much less match the magnificent horse bearing a conquering king. It is more than useless. It is a nuisance as it eats up anything, including the vegetables in the garden or even the lovely flowers left behind for our dearly departed at the cemetery.

No wonder many Chinese couples avoid having babies in the Year of the Goat. However, these couples may change their minds after watching National Geographic documentaries. They will be filled with admiration for the amazing feat (pun intended) of the surefooted and plucky goats frisking with abandon at the narrow edges of vertical cliffs.

And if only they could hear the heart beat or heart bleat of the goat. Continue reading “Cheers for the Maligned Goat”

Toward a More Precise Definition of Evolution

Much confusion arises in the debate on Evolution and Creation because the opposing sides are working with different meanings of evolution. It would be helpful to refer to the taxonomy of evolution given by Stephen Myer & Mike Keas. Principal Meanings of Evolution in Biology Textbooks: 1. Change over time; history of nature; any sequence … Continue reading “Toward a More Precise Definition of Evolution”

Much confusion arises in the debate on Evolution and Creation because the opposing sides are working with different meanings of evolution. It would be helpful to refer to the taxonomy of evolution given by Stephen Myer & Mike Keas.

Principal Meanings of Evolution in Biology Textbooks:

1. Change over time; history of nature; any sequence of events in nature.
2. Changes in the frequencies of alleles in the gene pool of a population.
3. Limited common descent: the idea that particular groups of organisms
have descended from a common ancestor.
4. The mechanisms responsible for the change required to produce limited
descent with modification, chiefly natural selection acting on random
variations or mutations.
5. Universal common descent: the idea that all organisms have descended
from a single common ancestor.
6. “Blind watchmaker” thesis: the idea that all organisms have descended
from common ancestors solely through an unguided, unintelligent,
purposeless, material processes such as natural selection acting on ran-
dom variations or mutations; that the mechanisms of natural selection,
random variation and mutation, and perhaps other similarly naturalistic
mechanisms, are completely sufficient to account for the appearance of
design in living organisms.

In my view, there seems to be evidence to support Evolution (1-4). However, the evidence for general evolution/Evolution (5) remains inconclusive, if not debatable.

Myer and Keas suggest that Evolution (6) in reality is a metaphysical theory. Continue reading “Toward a More Precise Definition of Evolution”
