Text 1
Evolutionary biologist Richard Dawkins argues that eusociality—exemplified by sterile worker castes in ants—is best explained by kin selection theory. Because workers share a high proportion of genes with siblings, helping the queen reproduce is genetically advantageous, even if the workers themselves do not reproduce. Under this view, altruistic behavior is driven by gene-level self-interest, rendering group selection models obsolete.
Text 2
E. O. Wilson contends that kin selection relies on highly restrictive parameters, such as haplodiploidy, which are absent in many eusocial species. Instead, Wilson posits that eusociality arose through multilevel selection: cooperative groups outcompeted less cooperative groups, driving the evolution of altruism. The genetic relatedness observed within colonies is a consequence of eusocial structure, rather than its primary evolutionary driver.
Based on the passages, how would E. O. Wilson (Text 2) most likely respond to Richard Dawkins's claim in Text 1 regarding the genetic relatedness of workers and siblings?
- ABy asserting that haplodiploid genetic sharing is actually far more common in non-eusocial species than Dawkins assumes.
- BBy suggesting that sterile workers do indeed reproduce, but their offspring are genetically distant from the colony's queen.
- By arguing that this genetic relatedness is a byproduct of how colonies are structured rather than the initial cause of eusocial behavior.Cevap
- DBy claiming that cooperative groups compete strictly on an individual genetic level rather than as collective units.
