Life Inside the Cell: Waking Up to the Miracle, part 1

Understanding the New Phylogeny of Angiosperms, part 1

[This is the first in a series of three posts, this one on life within the cell, the second, on the evolution of plants, and the third on the New Phylogeny and Eudicots.  While trying to understand the later, I found it necessary to better understand the others, what was behind this reorganization of how we look at plants.  To do that requires going back in time and scale to see what we are really taking about when we consider plants and the life within them.]

I begin here with the cell.  I will not spend time discussing its structure and various parts, the differences between those of plants, animals, fungi and bacteria.  That has been done by many others, elsewhere.  Instead I want to present here what I’ve learned about what makes the cell, its existence and life within it, so amazing, something that which should give us all pause, when we consider our own lives and what we do.  When scientists ‘split hairs’ in their arguments on which group to assign a species, when they attempt to link them to their ancestors, many of which are now long extinct, to understand their relationships with other organisms, they have a purpose.  They are looking much deeper into what a plant is, what constitutes life and how it evolved.  Phylogeny, the science that attempts to establish relationships between different organisms, different species, to link one to the other across time, is about both the history and the continuing journey of life on this planet.  It promises to tell us much about our own place as well as that of the hundred’s of thousands of other species with which we share it.  Ultimately, if we choose to understand this, it will change the way we garden and our relationship with the many landscapes that cover the Earth.  Our gardens are our own personal expressions, works of ‘art’, and must live within the parameters of life in effect on our little pieces of ground and the Earth.  They reflect our understanding of the limits and possibilities at work here.  The better that we understand this the ‘better’ our gardens will be, the more in synch they will be with life.   Continue reading
