Can some one help me with the natural science lab report it’s on Darwin’s theory with the different gallapos beak size, I will g
77julia77 [94]

Answer:

The basic principle of Darwinism is "survival of the fittest". Darwin's theory  stated that all species of an organism develop through the natural selection of small, inherited variations in organisms that increase the individual's ability to compete, survive, and reproduce in the wild.

Darwin's trip to the Galapagos Islands actually was the beginning of his Social Darwinism Theory. During his visit to the islands, Darwin noted that the  unique creatures were similar from island to island, but well-adapted to their environments. This led him to ponder the origin of the islands' inhabitants.

Darwin's finches (the Galapagos beaks) are considered to be the world’s fastest-evolving vertebrates. This is because their appearance and behavior quickly adapt to the closed and rapidly changing environment on the Galapagos Islands.
