Introduction to Psychology (PSY1003) - Theory of Evolution and Behavioural Genetics

Flashcards based on the lecture notes that cover key concepts in the Theory of Evolution and Behavioural Genetics.

What is the Theory of Evolution?

The Theory of Evolution is the only scientific explanation for the diversity of life on Earth that explains similarities across different life forms, changes within populations, and the development of new life forms.

What does the Theory of Evolution rely on?

The Theory of Evolution relies on the premise of abiogenesis, which is the origin of life from non-living matter.

Who co-developed the Theory of Evolution?

Charles Darwin and Alfred Russel Wallace co-developed the Theory of Evolution.

What are the three main factors in the Theory of Evolution?

Variation, Heredity, and Competition.

What is natural selection?

Natural selection is the process where those who are more effective competitors leave more offspring than those less effective, leading to adaptation to the environment.

Who is considered the father of modern genetics?

Gregor Mendel is widely considered the father of modern genetics.

What is a gene?

A gene is the fundamental unit of heredity and a segment of DNA occupying a specific site on a chromosome.

What is an allele?

An allele is a variation of a gene that affects the functionality of the protein produced by that gene.

What is zygosity?

Zygosity refers to the degree of similarity of the alleles for a trait.

What is the significance of mutations in genetics?

Mutations are random events in gene reproduction that can be deleterious, neutral, or beneficial, affecting evolution.

What did Hamilton's Rule state?

Hamilton's Rule states that altruism is favored when the product of relatedness and fitness benefit exceeds the fitness cost to the altruist.

What is the concept of kin selection?

Kin selection is an evolutionary strategy that favors reproductive success of an organism's relatives, even at a cost to the organism's own survival.
