What kind of organisms likely perished due to the increase of oxygen in the atmosphere three
billion years ago? heterotrophs cyanobacteria obligate aerobes obligate anaerobes facultative
anaerobes In the accompanying figure, note the variation in these closely related birds. What
does this illustrate\'? hybridization macroevolution hybrid inviability adaptive radiation
allometric radiation One critical requirement for life to arise on Earth was time for which to
occur? The salinity of the oceans to stabilize The Earth\'s various climates to stabilize
Molecules to accumulate and react with one another
Solution
6 . B cyanobacteria
Cyanobacteria increased in high amount 3 billion yrs ago dur to sudden increase in oxygen in the
environment which caused fires. Anaerobes couldn\'t survive, as oxygen was toxic for them.
