Interpretation of the Mars rover images

My interpretation of the images presented so far is: Mars has had life and it still has.

The key here is the theory by Steven Benner, that RNA, DNA and life was born in Mars and transported to Earth with meteorites. The life based on same DNA on Earth and Mars would have same origin: Mars. This would explain why we see same kind of animal and plant fossils on Mars as we have on Earth. The publications by science teams linked on this web-page also support the view that Mars is habitable and has had and may have life even today.

Instead of Benners theory of life born on Mars the panspermia theory by Fred Hoyle and Chandra Wickramasinghe could explain the observations from Mars maybe even better. That would take maybe one billion years or more away from time scale of birth of life: microbes based on same DNA would be available everywhere in our solar system when planetary bodies cooled enough. The theory by Benner is actually a subset of panspermia theory.

The structural Newberries (Opportunity, Sol 3064) could be fossil remains of plant-life in Mars. How far did evolution proceed in Mars? The animal fossils (Curiosity Sol-186, 107, 109) look like something similar we had on Earth seas before the time of dinosaurs. In Mars today microbial life would still remain (Sol-304). The microbes today can be of type chemolithoautotrophs and methanogens. The Sol-173 white objects which grow in size and the Blueberries resemble fungi.

In the images of this web-site, I count about 20 species of past life and about 16 species of currently living primitive life forms.

Below is summary image for candidates of currently living species on Mars (resembling microbial colonies, lichens and fungi...and possibly small bugs).
