This was Lamarck’s thesis. That the reason we see life at different levels of complexity is that life originates continually, then evolves, so lower life forms of life are members of younger lineages. Bacteria would be only slightly removed from the latest origination, for example. That said, no, it is not a current hypothesis of Biology that life is continually emerging from non living precursors. We haven’t observed any extant natural ecosystems that contain “proto-life,” nor something transitional between life and non-living potential precursors, nor chemical environmental conditions similar to those surmised to have existed 3.5 billion years ago on earth.

Because it’s an old volcano, but not so old as to have been eroded. Hawaiian volcanoes go through stages. Kilauea is very active and young. Mauna Loa is also active but not so young. Mauna Kea is much older and went though a late stage resurgence of activity that precedes dormancy. This is the source of the small cinder cones. Kohala is ancient and has been eroded away. Eventually Mauna Loa is go through the same process and make its own small cinder cones.
