An unbroken series of species arranged in ancestors to descendent sequence with each later species having evolved from one that immediately preceded it is called?
Correct answer: B. Phyletic lineage
- A. Biome
- B. Phyletic lineage
- C. Community
- D. Population
Explanation
A phyletic lineage is a continuous evolutionary sequence in which each species is considered to have descended from the species immediately before it. A population is only a group of organisms of one species in an area, so confusing an evolutionary sequence with a present-day group leads to option d rather than option b.

About Concept of Evolution
Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
