A new Earth is Discovered

The cross breeding reminds me a lot to the TV show V.

If it had life forms similar to what existed on Earth in the mesozic, I would either give it a pass or go and set up a hunting lodge. For the dinosaurs.

I am no scientist or expert, but I think that "life" is common elsewhere in the universe. Not only do I think it's common, but I also believe that life on similar planets would most likely evolve the same way as on earth, so an Earth like planet of similar size, gravity, distance from the sun and atmospheric composition would most likely have very similar life and similar organic processes.

If life exists on Titan though, it will be different to life on earth (methane based, able to survive harsh cold).

We'd most likely F up those planets too, consuming all their resources and killing off plants and animals to make space for more humans.

Let's hope we don't encounter an intelligent race that's even more ruthless or reckless than we are in that regard.

There are so many other factors involved, that I highly doubt we will find another planet that is "of similar size, gravity, distance from the sun and atmospheric composition." Our moon also played an important role in the evolution of life on Earth. As does our Sun, and even Jupiter.

A star that is dimmer than our sun might require the plant-life to become darker in color, possibly even black, in order to absorb as much sunlight as possible for photosynthesis to work. A brighter star that our Sol, may require life to develop some sort of protection against excessive UV light.

Planets can be larger than Earth in diameter and still have only 1G, if their density is less than 5.52 g/cm³ (the density of Earth). Conversely, planets can also be smaller than Earth in diameter and still have 1G, if their density is more than 5.52 g/cm³.

We also do not want to be around a star that is more than 1.5 solar masses. These types of stars live short lives, shorter than complex life requires. It took more than three billion years before complex life developed on Earth during the Cambrian Epoch some 540 million years ago. A star with 1.5 solar masses has a life-expectancy of only three billion years.
