Why do some organisms become more complex? Are there signs even now of life becoming more complex? Why don't other organisms become more complex?
There's a lot of speculation about why abiogenesis doesn't seem to occur on Earth any more, and the most common proposed reasons are that the conditions necessary for it to happen no longer exist here, and that the things life needs to get started would be eaten on a planet that is already over-run with life, so even if proteins and/or other new organics did start to form, established life forms would eat them before they could evolve into anything.
I don't really know why different organisms evolve at different rates, but I imagine it has a lot to do with environmental demands. Yes, there are signs that all life forms are continuing to evolve. Every time new life is made, it is slightly genetically different from whatever made it in the vast majority of cases, and that's all evolution needs to keep rolling: tiny changes accumulated over large periods of time.
Verbatim from the mouth of Jesus (retranslated from a retranslation of a copy of a copy):
"Do not judge, or you too will be judged. For in the same way you judge others, you too will be judged, and with the measure you use, it will be measured to you. How can you see your brother's head up his ass when your own vision is darkened by your head being even further up your ass? How can you say to your brother, 'Get your head out of your ass,' when all the time your head is up your own ass? You hypocrite! First take your head out of your own ass, and then you will see clearly who has his head up his ass and who doesn't." Matthew 7:1-5 (also Luke 6: 41-42)
