Question

Question restatement: Be aware that the prompt presents a single-choice item: 'Bees originated from wasps that abandoned depredation on other insects and adapted to collect nectar and pollen', with one answer option: 'This is likely true'.

Option analysis:
- Option: 'This is likely true'
  This statement aligns with the widely accepted evolutionary view that bees evolved from predatory wasps within the Apoidea lineage. The transition described—shifting from preying on other insects to collecting nectar and pollen—fits the core idea of a diet and lifestyle shift that accompanies the emergence of bees as specialized pollinators. This interpretation is supported by morphological and genetic evidence showing similarities between bees and certain wasp lineages, as well as the ecological rationale that nectar and pollen exploitation would yield a reliable food source while fostering plant–insect mutualism through pollination.

Why this reasoning fits biology:
- The ancestry of bees is often traced to predatory wasps, with bees representing a lineage that adopted a diet based on nectar and pollen rather than predation on other insects.
- Morphological traits such as body hairiness and modifications for pollen collection can be seen as adaptations consistent with a shift toward nectar/pollen foraging.
- Ecological logic supports a gradual transition: an ancestral wasp exploiting floral resources could steadily become more specialized in nectar/pollen gathering over time, leading to the diversification of bees as pollinators.

Absence of alternative options:
- There are no other answer choices to evaluate, so we cannot compare against competing hypotheses in this item. However, given the standard scientific consensus, the proposed origin pathway is considered plausible and widely accepted.

In summary, the statement describes a credible and well-supported evolutionary scenario for the origin of bees, reflecting how a shift from insect predation to nectar and pollen collection would naturally lead to the emergence of bees as a distinct pollinating lineage.
