Final answer:
Storm-petrels, with a lifespan of 30 to 40 years, are more likely to have a longer pre-reproductive period when compared to thrushes that live only 3 to 4 years. This is consistent with patterns observed in birds, where species with longer lifespans tend to mature later and provide more extended parental care, such as the Great Frigatebird that cares for its young for 20 months.
"The correct option is approximately option A"
Step-by-step explanation:
Based on the information provided, one could make an educated guess that storm-petrels have the longer pre-reproductive period compared to thrushes.
This inference is drawn from the general trend observed in birds where species with longer lifespans, such as albatrosses that do not start breeding until age 8 or 9 and can live up to 60 years, tend to have a delayed maturity and a more extended period of juvenile dependence. Similarly, the Great Frigatebird provides intensive care for its young for 20 months, indicating a longer dependency period which often correlates with a later age of maturity.
In contrast, species with shorter lifespans, like thrushes that live only 3 to 4 years, are likely to mature and reproduce quickly to ensure their genetic contribution to the next generation. Therefore, the storm-petrels, with a lifespan of 30 to 40 years, are more likely to have a longer pre-reproductive period than thrushes.
