Concept explainers

Evolutionary lineages

An evolutionary lineage is a series of populations of organisms that descend from a common ancestor. Each species in the lineage is the direct consequence of evolutionary change from a common ancestor. A phylogenetic tree is generally used to display lineages visually. Lineages are components of the phylogenetic tree of life. Molecular systematics procedures are widely used to predict lineages.

Question

The difference between sympatric and parapatric speciation is ___ .
a. parapatric speciation occurs only in velvet walking worms
b. sympatric speciation requires a barrier to gene flow
c. the extent of overlap in range
d. reproductive isolation does not occur

Definition Definition Process by which new species arise. This occurs when populations of a species become isolated and diverge, developing unique traits through natural selection, genetic drift, or other mechanisms. Over time, these differences accumulate until the populations can no longer interbreed and are considered separate species.
