Why did Darwin think morphology was the "very soul" of evolution? Why was the pattern of "tiered resemblances" significant for understanding evolution?
a) Morphology showcases the diversity of life forms, and tiered resemblances illustrate the progression of evolution from simpler to more complex organisms.
b) Morphology helps in classifying organisms, and tiered resemblances reveal patterns of geographic distribution.
c) Morphology is crucial for understanding genetic mutations, and tiered resemblances demonstrate the role of natural selection.
d) Morphology reflects an organism's behavior, and tiered resemblances indicate ecological niches.
