Many scientists believe that life formed in the oceans. Does this mean that the rest of the planet was just barren rock before the first sea creatures crawled from the sea? How did the "seeds" for trees form anyway? Please include any sources. Thank you very much!

The first trees (big plants [30 meters] with woody stems) evolved about 360 million years ago.

The first land plants didn't have seeds they were spore plants...such as ferns and such. After land plants started to develop then the animals started heading for land. I am sorry that I can not remember how many millions of years ago this was...I just finished teaching this to my class about a month ago...but I also teach all 5 subjects so it is hard for me to remember exact details of all that I teach.

since approximatly 235 billion years ago. the first fungue became noticable about the end of march, and grew from a single rock, which the atmospheric pressure build up effected, by making the molecules in the water extract. If you really want details, go ahead and email me.. Bye now!

Up to now, the earliest land plant remains found (Cooksonia) date from the Silurian period
