What impact does a structural increase of humidity and temperature have on the biosphere around the equator?

"Fred Hoyle invigorated and championed the idea of panspermia with his colleague Chandra Wickramasinghe as it deemed to be a plausible tweaking knob for the chance genesis of life. In fact, the theory can add several billions of years to allow the time-thirsty process to materialise.

Similar to Darwinism, panspermia was not expected to address the correct details of the origin of life question but rather suggests the possibility of simple life form, such as spore-forming bacteria, being able to jump between a network of suitable planets throughout the vast universe. The occasional visitors then either initiate the evolution of life from scratch in a newly formed and life-friendly planet or intermittently influence the evolution of already existing flora and fauna.

The caveat was that the theory proposes the whole universe, not only a local ecology on Earth, the arena of evolution. It also takes the idea of evolution to the extreme by unintentionally suggesting that unintelligent and blind life has the capability to randomly evolve not only to survive in natural local environment on Earth but also to be top-notch fit to survive in the whole of the universe. It has been made fit enough to survive the completely unpredicted and uncharted hazardous journey consisting of three life endangering stages including departure from mother planet, interstellar and intergalactic journey and arrival in a new suitable planet.

According to this theory, life and its evolution are therefore not exceptional to one single planet. The evolution process in one suitable planet is also not responsible for all different organisms on it. New microorganisms are continuously being evolved in all suitable planets and are being transferred throughout our universe. For example, Hoyle and Wickramasinghe suggested that H1N1 virus which was the cause of 1918 flu pandemic did not evolve in our planet but in a faraway one and then somehow transferred into space and arrived on Earth within a shower of meteorites.

Life has been found to be present very soon after the formation and suitability of the planet earth which apparently is considered not to be adequate enough for chance-time to produce it..."

I have tried to further analyse this theory in the appendix of the following document. I welcome any comment, criticism, correction and addition.
