Systematics:Digging Deeper

Worldviews are not enough

For Christian critique of science and science teaching

we need a systematic understanding of how

beliefs influence science

Tree ofLife

General PhilosophyWhat is Biology?

“Life is never a material, a substance to be moulded. If you want to know, life is the principle of self-renewal, it is constantly renewing and remaking and changing and transfiguring itself.”

Boris Pasternak (1890-1960)

(Doctor Zhivago)

Philosophies of Biology

• Atomism – all wholes are explained by analysing them into their parts.

• Mechanism – All events are explained by preceding events which are their causes.

Paradigms in Genetics

• Mendelism

• Weismannismgerm line theory

particulate heredity

Two key paradigms:

Mendelism – The factors governing characters are material, hereditary particles (‘atoms’) – now called ‘genes’.

Weismannism – Heredity is a function of the germline only. The germline gives rise to the body (soma); the body does not affect the germline.

• DNA reductionism is like saying the bumps on a CD

• create both the music and the CD player.

• DNA encodes the building materials (proteins), but not the architect’s plans.

• Heredity and development never start with just DNA, but always with whole cells, whole organisms.

Is there a scientifictheory of

evolution?

How? No theory!

(1) Embryological Development

How? No theory!

(2) Evolutionary Development

CONCLUSION:How can we

shapebiology?

• through understanding how beliefs influence science

• through developing and applying a Christian philosophy of science

• through worldview analysis
