Infants and Apes Remember Things Similarly
　　
　　Infants and apes apparently adopt the same tactics（1） for remembering where things are, but as children develop their strategies change, a new study shows.
　　The findings might reveal in part how the minds of our distant ancestors shifted gears（2） to embark（3） on the road toward humanity.
　　There are two basic strategies animals use to remember where things are. Either they remember a things features, such as whether it was a banana, or they remember its place in space, such as left.
　　All animals scientists have tested seem to employ both strategies. However, if experiments are rigged（4） such that animals had to choose between the tactics, some species, such as chickens and toads（5）, prefer a feature-based strategy. Others, such as fish and dogs, favor a place-based strategy.
