BEARING FRUIT BY
MALE CARICA PAPAYA SIMILAR TO THAT OF A FEMALE PLANT PROVIDES A
POTENTIAL SOURCE FOR UNDERSTANDING HOMO SAPIENS EVOLUTION
RAJPUT MUHAMMED TARIQ
Abstract:
The papaya plant Carica papaya
(family: Caricaceae), locally known as Papita, is cultivated commonly in
different parts of Sindh-Pakistan specially in Karachi. It was reported
hermaphrodite. Recently it has been reported to be an important plant,
due to having X and Y chromosomes. As it has been already reported that
the papaya sex chromosomes have virtually all of the features that the
human sex chromosomes have. In the present paper observations are made
that not all the male papaya plants due to male (mM) characteristic but
some of them are hermaphrodite in characteristic (mmM = XXY = mMh =
XYh), exactly identical to a normal male and have been recorded bearing
fruits like the female papaya plants (mm = XX). This characteristic of
the male papaya plant provides a clicking source for positive
understanding of Homo sapiens evolution from a male (Aadam), that
how the female sex chromosomes (XX) were evolved from a hermaphrodite
(XXY). This theory has been proposed as “Aadam Hypothesis”. In the
present paper the theory of “Aadam Hypothesis” has been also supported
by Natural Method of Propagation (NMP) of two different plant species
Bryophyllum pinnatum and Kalanchoe verticillata (syn K.
tubiflora) having budding system for the propagation of fertile
plantlets on scientific grounds.
