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.
