An archaeologist working at a site in Arizona found pottery shards, corn cobs and squash seeds, and lengths of rough wooden polls in the structures. The
archaeologist reported at a news conference that the ancient people were
farmers. What evidence did the scientist use to support this report?

(it’s a observation and inference question! i need two observations and two inferences)

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
