Scientists have been trying to determine the characteristics of
the so-called “Last Universal Common Ancestor,” or LUCA. How can
they do this? A professor at the University of Montreal says
they “identify common genetic traits between animals, plants,
and bacteria” and use them to create a “tree of life.” In other
words, any characteristics that are similar must go back to the
original common ancestor of life. Researchers have decided that
this early ancestor was sensitive to heat and could not survive
in the heat that supposedly characterized the earth at its
beginning. So they conclude that LUCA must have found a little
“mini-climate” area that was cooler so it could develop and
evolve. Doesn’t this all sound a little far-fetched? Scientists
insist that common characteristics among organisms mean a common
ancestor. Creationists, however, have long taught that this
shows a Common Designer. God made animals and people with some
similar characteristics. But humans and animals and plants are
also very unique. T
