How old is the earth?
Does it matter? On today's
podcast we will see how biological essentialism implies a young earth. Is a bat a flying rat? Have kangaroos always been kangaroos? What is a liger? What are ORFan (orphan) genes? Learn more here about these fascinating
topics. Biological essentialism teaches
that organisms vary within limits (see ch. 3 of YES - Young Earth
Science). Richard Dawkins made his
opinion on essentialism clear:
... essentialism has been applied to living things and Ernst Mayr blamed this for humanity’s late discovery of evolution - as late as the nineteenth century. If, like Aristotle, you treat all flesh-and-blood rabbits as imperfect approximations to an ideal Platonic rabbit, it won’t occur to you that rabbits might have evolved from a non-rabbit ancestor. [1]
Andrew Shtulman, Psychology Professor at Occidental, gave
a talk at UCLA in 2011 on the topic of "Cognitive constraints on the
understanding and acceptance of evolution." He recognized that essentialism is a primary
reason why people fail to adopt Darwinism. Children at an early age develop an essentialist
WorldView. They quickly come to realize
that crabs and seahorses belong to different Essential Types of Life (ETL's).
ORFan
genes are unique to certain organisms and no similar genes have been found in
supposedly related animals.
That is, there is no apparent "parent" genes in other organisms. For instance, more than half of the proteins of the
leaf-cutter ant (see above) are unique to itself among the expressed proteins.
Biological essentialism leads to catastrophism and that favors a young earth perspective. What evidence would be required to verify a young earth? Let us hear from you: YoungEarthScience@yahoo.com
