There is a lot of mis-information on internet concerning the red rains
in Kerala, India. The mis-information resulted from mis-identification
of the material contained in the red rains. The mis-identification
resulted from not knowing anatomy.

Example 1: The official report (
http://web.archive.org/web/20060613135746/http://www.geocities.com/iamgoddard/Sampath2001.pdf
) by the Indian government concluded the red rains primarily contained
spores of a type of algae named Trentepohlia.

The spores of Trentepohlia are more or less round-shaped as shown in
Fig. 6 ( http://www.wretch.cc/album/show.php?i=lin440315&b=29&f=1782760665&p=37
) of the official report. The round-shaped Trentepohlia spores in Fig.
6 resulted from cultivation. Those spores are different from many
oblong particles in the original, uncultivated samples shown in Fig. 2
( http://www.wretch.cc/album/show.php?i=lin440315&b=29&f=1782760666&p=38
). So, the red rain did not primarily contained spores of
Trentepohlia.

Example 2: Figure 2 of the official report failed to recognize
fossilized mammalian red blood cells (
http://www.wretch.cc/album/show.php?i=lin440315&b=29&f=1782754564&p=39
). They are fossilized, because they did not disintegrate even when
they were heated to 300 degrees Centigrade (
http://www.wretch.cc/album/show.php?i=lin440315&b=29&f=1782745568&p=40
& Fig. 4b at http://arxiv.org/ftp/astro-ph/papers/0310/0310120.pdf ).
No living cells could stand the heating without disintegration.

More mis-information: Some people claimed the biological cells in the
red rain could reproduce themselves at 300 degrees Centigrade. In
fact, the red rains also contained relic fat cells and relic fat
globules (lipid droplets), both of which contained lipids. Minute
lipids could seep out of relic fat cells or relic fat globules when
they were heated to 300 degrees C.

Concerning DNA, some people said there was no DNA while some people
said DNA was possibly found in the red rain particles. Red blood cells
and fat globules contain no DNA. White blood cells and fat cells do
contain DNA. Since they were from Mars and billions of years old,
their DNA could not be properly recognized.
