In 1998, archaeologists found a forty-million-year-old baby bird frozen in amber. Although the sample was not large enough to determine its flying habits at such a young age, scientists guessed that the three-day-old bird would have been able to fly from birth and might have been hunting at the time the tree sap fell onto the bird, preserving it for millions of years. This proves how different this species of birds is from modern birds; modern birds depend on their parents for care for 2 to 3 weeks, while this ancient specimen was able to hunt right out of the nest. The reasoning in the argument is most vulnerable to criticism on the grounds that the argument ['does not consider the possibility that immediate flight was a risk to the species.', 'draws its conclusion from data that cannot be proven true.', 'confuses the cause of death with the effects of death.', 'takes an inconsistent stance regarding its premise and conclusion.']
