375 million years ago, the population of organisms we call Tiktaalik had variation in many aspects of the appendages including the
bones, muscles and nerves. What evolutionary force was likely most responsible for rapid adaptation and the relatively rapid
evolution of limbs in this lineage?
(A) natural selection
(B) NONE of these
C) mutations
D genetic drift
(E) speciation
The presence of homologous structures in two different groups of organisms suggests that (a) the organisms evolved from a common ancestor (b) convergent evolution has occurred (c) they belong to a polyphyletic group (d) homoplasy has occurred (e) independently acquired characters may evolve when organisms inhabit similar environments
In what way does the modern synthesis strengthen scientific understanding of evolution? (a) is based on the sequence of fossils in rock layers (b) uses genetics to explain the source of hereditary variation that is essentialto natural selection (c) was first proposed by ancient Greek scholars (d) considers the influence of the geographic distribution of organisms on their evolution (e) is reinforced by homologies that are explained by common descent
