N S And G M- Darwins Theory Flashcards
Who invented this theory?
Charles Darwin and Alfred Russel Wallace
What is genetic variation?
The characteristics of individuals/organisms vary (due to difference in genes)
What is environmental change?
Conditions within a area change E.g lack of food will cause more competition between organisms
Natural selection?
By chance/luck variations of some creatures make them better at coping with the change than others and more likely to survive (survival of the fittest)
What is inheritance?
The survivors (fittest) breed and pass on their variations (that are for survival)to their offspring therefore the next generation contains more individuals with the “more advanced adapted variations”
What is evolution?
If the environment remain changed (temperature,food) natural selection occurs repeatedly and as new species evolves with all the individuals having the ‘better adapted variations’
What is genetic analysis?
The overall process of studying and researching in fields of science that involves genetics and molecular biology
