    Did anybody put B for the table question where they are geographically isolated?
    I put c because I thought the smaller the population the large the effect of genetic drift

    I personally thought it was an OK paper but still understand the anger of some as there was a lot of hit and miss questions.

    The genetic drift one? Yes, because they had the biggest decrease in recessive alleles so the amount genetic variation had decreased, because increase in dominant allele frequency meant there was less genetic variation as all the individuals had similar genotypes

    Isolation can occur in three forms: Mechanical, Behavioral, Seasonal. The questions spoke about cant reproduce therefore that is mechanical or no?
    There was a bloody road separating them so geographical

    My bad I meant to talk about the question comparing the S drug to the M drug, I talked about the receptor being the incorrect shape on the previous question
    I said the m drug was a better fit to receptor

    It was insight learning and not operant conditioning, OC is learning by reward and punishment whereas insight learning is using reasoning and judgement from past experiences
    But surely the bin is a reward, so if the raccoon learns to push the bin lid off it is rewarded? Raccoons go through multiple bins each day, so they're repeatedly presented with a bin and they've learnt that if they interact with the bin, they're rewarded?

    I was 50/50 on putting operant vs insight but put operant because they phrased it as "the raccoon learns to push the bin lid off"
