1

sexual selection

Sexual selection applies to those characteristics that provide
individuals with advantages in gaining access to mates.

2

female choice

"intersexual choice"; when competition to be chosen by the female is the driving factor for mating

3

parental investment

asymmetries between the sexes in
the amount of effort that each parent puts into raising the offspring

4

handicap hypothesis

Male adornments are chosen
by females for their
conspicuous and costly nature

Females choose males which
show conspicuous and costly
adornments as a sign of
genetic quality

Male features signify
genetic superiority i.e.
‘healthy-offspring’

5

parasite theory

male
adornments evolved to demonstrate to females that they are free from parasites

6

Muller's ratchet

states that each time a
harmful mutation arises in an individual in an asexual population it will be
passed on to all of its offspring

7

tangled bank

The Tangled Bank Hypothesis proposes that sex evolved in order to prepare offspring for the world around them.

8

the Red Queen

proposes that organisms must constantly adapt, evolve, and proliferate not merely to gain reproductive advantage, but also simply to survive while pitted against ever-evolving opposing organisms in an ever-changing environment.

9

arms race

a continual evolutionary battle

10

intrasexual selection

when same-sex competition is a primary driver for mating

11

runaway feature

when one feature "runs away" from its original
function and becomes selected purely on the basis of its attractive qualities.
