Survival of the fittest- Darwin's Finches
The Galapagos' Islands are home to 13 different species of finches. The main difference between the species was size and shape of their beaks. The finches beaks were different because they lived in different Islands in different environments. The environment did not cause the differences in beaks, but the finches with beaks best suited for the islands local food supply would have an advantage. Therefore finches best suited for the food source would survive in greater numbers. -
Darwin's three observations
Three observations that allowed Darwin to develop his theory were:
1.)" The individuals in a population display a variation in traits such as color, behavior, size and shaped due to genetic variation."
2.)" Some of the traits passed down from parents to descendants and are heritable."
3.) The parents in the population overproduce offspring so that some will not survive." -
Darwin's three observations Continued
based on these three observations Darwin proposed that traits that made the individual fitter would be the individuals that survived, while the least fit would die off. -
