Answer:
STATEMENT OF HYPOTHESES BASED ON RECENT AND
FORMER EXPERIMENTS.
i. The Specific Odor. —¿The mother-ant transmits to her off
spring the distinctive odor which is identical for ants of all ages
and of both sexes within the species. This odor is appreciated
among ants by organs near the proximal end of the funiCle)
2. Progressive Odor. —¿Female ants, including queens and
workers, have, besides their specific odor, an odor which may be
termed progressive. Queens of different lineage have different
progressive odors. In a queen this odor is either unchanging or changes very slowly, and it is similar to that of her newly
hatched female offspring. a. As worker-ants advance in age their progressive odor
intensifies or changes to such a degree that they may be said to
attain a new odor every two or three months. This progressive
odor is appreciated among ants by organs in the penultimate
joint of the funicle.2
b. Male ants have no progressive odor unless it be super
ficially incurred through association with workers; but the male
carries latent in his spermatozoa the progressive odor of his
mother. In other words the progressive odor is always recessive
in the male ant. c. The progressive odor of each new generation of females is
