Document Summary
Will always come back to evolution (core theme and unifying concept) therefore can be explained by evolution. Processes are shared throughout organisms (life processes) Also explains diversity (evolve= can be substituted as change however in a biological context evolution means genetic diversity among individuals in a certain population) Individuals do not evolve but populations do (populations evolve through reproduction because genetic traits are passed which would mean that the ones that are favourable will most likely be passed due to increase in fitness) Heritability- able to be inherited from parent to offspring (therefore favoured genes are passed) The cuttlefish changes skin tone colour to protect itself and is able to sense environment through eyes (eyespot). Sunlight is a signal which initiates a response, this can be called a transduction pathway at the molecular level. Transduction- physical quantity such as light can be converted into an electrical signal such as skin tone change.
