What is the Universal distribution of Iodine
and Higher life? Possibly depends on events like the collision of two
neutrons stars where LIGO detected gravitational waves.

As
I reported earlier, collision of two neutron stars has led to the
higher life forms that evolved on this planet because it produces
Iodine. Iodine is essential for Amphibia to complete their life cycle
and thyroid hormones using iodine are found in Amphioxus, Cyclostomes
and other evolutionary relatives. Iodine and thyroid
hormones are critical for sustaining higher animal life. It is also
found in some Protists.
We would not exist if the chordates and
amphibians hadn't evolved. The probability of such events are much
smaller than stellar explosions in general. If Iodine is a prerequisite
for higher life evolution, this could mean that life is more rare than
we thought possible. Iodine might also be produced in a few other
stelllar events and dispersed but some of these lead to Black holes.
In
the search for life we might want to focus more attention on rocky
water worlds that have iodine. Is it a prerequisite for primitive
microbes? That can be answered by Iodine presence or absence statistical
survival tests in photo-ferrotrophic green sulphur bacteria, alpha
proteobacteria and SAR II(our mitochondria), archaea (our ancestors) and
cyanobacteria (our oxygen).
