adaptation Flashcards
behavioral
the things an organism does to survive
structural
physical features of a organism that help them to adapt
physiological
permit organism to perform special function
mimicry
harmless species resemble (mimic) a harmful species so predators will avoid them because they think they are harmful
variation
structural, functional or physiological differences between individuals. It is important to note that not all variations become adaptations
how does variation lead to adaptation? peppered moths
darker-coloured moths were extremely rare. 50 years later, dark coloured moth populations increased. this is due to the behaviour, genetic make-up and the environment they lived in
what is the difference between adaptation and variation?
adaptation is the process that helps an organism survive and reproduce in a particular environment and variation is the differences between individuals
mutations
a permanant change in the genetic material of an organism
selective advantage
a genetic mutation that improves an organisms chance of survival in a changing enviroment
