Recent studies reveal extraordinary biological phenomena. Iberian harvester ant queens can produce hybrid offspring using sperm from another species, effectively cloning males to sustain hybrid worker populations, a form of sexual parasitism and genomic domestication. Ancient DNA sequencing from mammoth teeth and bones uncovers microbial communities dating back over a million years, including pathogens related to modern species. Additionally, research elucidates brown widow spider mating tactics and cranial morphology variations in flying squirrels linked to diet and habitat, expanding understanding of evolutionary adaptation.
