Evolutionary models suggest that the cost of a signal can ensure its honesty. Empirical studies of nestling begging imply that predator attraction can impose such a cost. However, parents might reduce or abolish this cost by warning young of the presence of danger. 我已經刪掉後半部了 可以幫我解釋一下COST跟HONESTY的意義嗎? 謝謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.217.122.59
