Question

True or false: What we call ' Oxygen Revolution' happened due to oxygenic photosynthesis performed by dinoflagellates.

True or false: Only vertical gene transfer (parent to offspring) affects the diversity of branches on the tree of life.

True or false: Biogeography can alter positions of continents and so climate.

True or false: Permian Extinction shaped biodiversity in a way that it gave opportunity to the modern taxa.

True or false: Ediacaran fossils are a special case because they capture a wide range of soft-bodied organisms that are rarely preserved in the fossil record at a time when the diversity of metazoans was greatly increasing.

Answer 1

1) False

oxygen revolution happened due to Cyanobacteria

2) True

vertical gene transfer from parents to generation mainly affects the biodiversity as it is the main source of generation of variation in the offsprings .

3) True

The position and the movement of the tectonic plates influences the distribution of life on the earth

4) True

about 250 million years ago at the end of Permian period killed around 90% of planet’s species and only 5% of animal species in sea survived

5) True
