What does the study of biogeography contribute to our understanding of evolution?
It explains the precise mechanisms of genetic mutations.
It proves that acquired characteristics are inherited.
It demonstrates the spontaneous generation of life.
It shows how the distribution of organisms reflects evolutionary history and geological events.
‘Every cell of the body contributes gemmules to the germ cells and so shares in the transmission of inherited characters’, this theory is known as
Pangenesis
Lamarckism
Germ-plasm theory
