How did Darwin\'s view of descent with modification differ from the common perspective about relationships among living things? A) Darwin viewed closely related species as those with shared ancestors. B) He thought that geographic distributions were not informative about relationships between species. C) Darwin did not believe in extinction. D) He determined relationships among species based on their outward forms alone. Solution D) He determined relationships among species based on their outward forms alone. The theory of descent with modification proposes that all the organisms were evolved from the pre-existing ancestors and the theory of natural selection describes how changes have occurred in some organisms during the evolution process. Darwin studied only the outward forms, but the genetic data relating the species was not included..

1. How did Darwin's view of descent with modification differ from the common perspective about
relationships among living things?
A) Darwin viewed closely related species as those with shared ancestors.
B) He thought that geographic distributions were not informative about relationships between
species.
C) Darwin did not believe in extinction.
D) He determined relationships among species based on their outward forms alone.
Solution
D) He determined relationships among species based on their outward forms alone.
The theory of descent with modification proposes that all the organisms were evolved from the
pre-existing ancestors and the theory of natural selection describes how changes have occurred in
some organisms during the evolution process. Darwin studied only the outward forms, but the
genetic data relating the species was not included.
