Apologetics - Biology Test Study Guide

Natural Selection

A mechanism that promotes adaptation and modification of existing systems through random variation.

Irreducible Complexity

A characteristic of systems with multiple interacting parts that only function when all components are present.

Darwinian Theory

A theory that proposes natural selection as the mechanism for evolution, but is challenged by complex biological systems.

Complex Organ

A biological structure that cannot be formed through numerous, successive, slight modifications according to Darwin.

Gene Regulatory Networks

Elements in vast, dynamic, intercellular signaling networks controlling the cell.

Macroevolution

Fundamental changes in the body plan of an animal, requiring significant genetic mutations.

Waiting Time Problem

The issue that the time needed for genetic changes to occur through random mutations is longer than the time available for evolution.

Coordinated Mutations

Genetic changes that only together produce beneficial traits, complicating evolutionary explanations.

Common Descent

An idea based on observations of relationships among species that doesn't explain how biological changes occurred.

Optimization

The process of refining existing systems or traits, not creating new ones.

Cambrian Explosion

A historical event characterized by the sudden appearance of most major animal body plans without precursors.

Junk DNA

Previously termed non-functional DNA; now recognized to have important regulatory and operational roles.

Evolutionary Developmental Biology (Evo Devo)

A discipline aiming to address problems in evolutionary theory by manipulating gene networks.

Empirical Data

Data obtained through observation or experimentation, highlighting shortcomings of Neo-Darwinism.

Symbiotic Representation in Life

The idea that living organisms embody a symbolic representation of themselves, suggesting a mind is necessary for abstract realities.
