Nick Lane Quotes

Nothing is more conservative than a bacterium.

The myosin in our own skeletal muscles is more closely related to the myosin driving the flight muscles of that irritating housefly buzzing around your head than it is to the myosin in the muscles of your own sphincters

It seems that all eukaryotic cells either have, or once had (and then lost) mitochondria. In other words, possession of mitochondria is a sine qua non of the eukaryotic condition

The story of evolution is more dramatic, more compelling, more intricate than any creation myth. Yet like any creation myth, it is a tale of transformations, of sudden and spectacular changes, eruptions of innovation that transfigured our planet, overwriting past revolutions with new layers of complexity. The tranquil beauty of our planet from space belies the real history of this place, full of strife and ingenuity and change. How ironic that our own petty squabbles reflect our planet's turbulent past, and that we alone, despoilers of the Earth, can rise above it to see the beautiful unity of the whole.

The point I want to make about methanogens is that they were the losers in the race through a bottleneck, yet nonetheless survived in niche environments. Similarly, on a larger scale, it is rare for the loser to disappear completely, or for the latecomers never to gain at least a precarious foothold. The fact that flight had already evolved among birds did not preclude its later evolution in bats, which became the most numerous mammalian species. The evolution of plants did not lead to the disappearance of algae, or indeed the evolution of vascular plants to the disappearance of mosses.

We should not be too quick to dismiss our own [ocular] arrangement. As so often in biology, the situation is more complex.....we have the advantage that our own light-sensitive cells are embedded directly in their support cells (the retinal pigment epithelium) with an excellent blood supply immediately underneath. Such an arrangement supports the continuous turnover of photosensitive pigments. The human retina consumes even more oxygen than the brain, per gram, making it the most energetic organ in the body.

Our terminal decline into old age and death stems from the fine print of the contract that we signed with our mitochondria two billion years ago.

The shrimp's protein and ours are not exactly the same, but they're sosimilar that if you turned up in court and tried to convince a judge that yourversion was not a badly concealed plagiarism, you'd be very unlikely to win.In fact, you'd be a laughing stock, for rhodopsin is not restricted to vent shrimpand humans but is omnipresent throughout the animal kingdom.... Trying to persuade a judge that your rhodopsin is not plagiarisedwould be like trying to clajm that your television set is fundamentally differentfrom everyone else's, just because it's bigger or has a flat screen.
