Could the blue jays ever have had thin beaks? (PLEASE ANSWER ASAP!! I WILL AWARD BRAINLIEST) (image below)

1. No blue jays could have been born with a thin-beak trait because none of the adult blue jays had that trait to pass down.

2. No blue jays could have been born with a thin-beak trait in the past, but some with that trait could be born in the future if the environment changes to have pine cones with seeds.

3. A blue jay could have been born with a mutation in its genes for the thin-beak trait and lived for a little while, but it would have been more likely to die before it had offspring.

4. A blue jay could have been born with a mutation in its genes for the thin-beak trait, but having a mutation in its genes would have caused it to die when it was born.

Answer:

i believe the answer is 2)

Explanation:

because birds that eat seeds need to have thinner beaks in order to get to the seed. seeing as how their beaks are currently too large for that, they wouldn't be able to reach the seeds- they would have to adapt to the new environment **if that were to happen**

good luck :)

hopefully, this helps

**please let me know if this was incorrect**

have a nice day !!
