INTRODUCTION

Welcome to the next post in this series of sharing posts. Our theme in this one is nature, and while most of the pieces I am linking to are about the present, we being with a journey back to…

385 MILLION YEARS AGO

This was when our ancestors first moved from the sea to the land. The usual reckoning is that the key development that led to this happening was to do with limbs, which would seem to be common sense. However, according to this piece on astrobio.net, there is an alternative view now being proposed that the key development was actually to do with vision not limbs. As is now my custom I am using an image to link to the full article:

Now we move back to the present, and we start with a distressing story about…

RHINO POACHING

As wild rhino numbers continue to decline the poachers whose activities are most directly responsible for this decline are becoming more brazen. This story concerns a Rhino in a zoo which was shot for its horn. The saddest aspect of this story is that the wealthy Chinese who buy most rhino horns do so based on alleged properties of the substance that are entirely fictional – this is the same stuff that our own finger nails are made of, and no one would pay big money for those. As usual, the link is in the accompanying image.

I am branch secretary of NAS West Norfolk and #actuallyautistic (diagnosed 10 years ago at the comparatively advanced age of 31). I am a keen photographer, so that most of my own posts contain photos. I am a keen cricket fan and often write about that subject. I also focus a lot on politics and on nature.
