51pWhat is the point made in paragraphs 1 and 2?

In the past the male Y chromosome used to be more substantial.

Men are hardly able to cope with challenges of their male pride.

Procreation may one day be realised without male participation.

The male physique is deteriorating at an alarming pace.

a He said: "Everyone agrees the demise of the Y chromosome, if it
happens, does not mean the demise of the human male. All that will
happen is that the process of sex chromosome evolution will start
again."
b That may be wishful thinking. A few hundred million years ago, the X
and Y chromosomes were the same size. Today, the Y chromosome
holds fewer than 30 genes, against the X chromosome's 800 or so. "If
you draw a straight line, the Y chromosome's demise would come four
or five million years from now," said Darren Griffin, professor of
genetics at the University of Kent in Canterbury, who nevertheless
remains undecided on the issue.
c The researchers studied the genes on the human Y chromosome and
compared them with those on the Y chromosomes of chimpanzees
and rhesus macaques. The latter split from the human lineage 25m
years ago. Hughes found that only one gene had been lost from the
human Y chromosome since then. The rapid decline of the Y
chromosome seems to have ground to a halt. "We are hoping this
evidence will put the extinction of the Y to rest once and for all,"
Hughes said.
d This prospect is seriously debated among biologists. At a genetics
conference in Manchester last year, half of those attending thought the
Y chromosome was bound for oblivion. Hope may be at hand, though.
Writing in the latest issue of Nature, Jennifer Hughes and her
colleagues at the Whitehead lnstitute for Biomedical Research at MIT
come out in support of the Y chromosome's chances of survival. "We
can confidently say that the decay of the Y chromosome has come to
a halt, and that would portend very well for its future," Hughes told the
Guardian. "There are far more things to worry about than this."
