Question

Because finches with large beaks gave birth to chicks with bigger beaks:

a-This example gives evidence for the inheritance of acquired characteristics
b-Beak size is a heritable trait
c-Conspecific nest parasitism probably doesn't occur
d-Beak size does not influence survival

Answer 1

The inheritance of acquired characteristics is not supported by the example of finches with large beaks giving birth to chicks with bigger beaks. Beak size in finches is a heritable trait influenced by natural selection.

Step-by-step explanation:

The example of finches with large beaks giving birth to chicks with bigger beaks provides evidence for the inheritance of acquired characteristics.

This concept suggests that characteristics acquired during an individual's lifetime can be passed on to their offspring. However, in the case of beak size in finches, it is actually a heritable trait influenced by natural selection.

The variation in beak size is inherited, and finches with larger or smaller beaks have different survival rates depending on the availability of food sources.
