Image of the day – 93

What’s in an image? Sometimes quite a lot, more than meets the eye. I’m posting an image every two days or so.

Like all plants and animals, bees are pretty well suited to the actions they need to perform to live and reproduce. That’s what evolution does, it homes in on the best shape and size of wings, the optimum size for flight muscles, best arrangement of hairs on the legs to brush loose pollen towards the pollen sac for collection and transport, the best mouthparts for collecting nectar and so forth.

Quite a challenge, and an astounding achievement, but entirely doable by making small, random changes and selecting the best.

Here’s an example to make that bold claim clearer. If a random change enables the worker bees to carry on just a few days longer in the autumn, the hive will have slightly larger stores of honey for the coming winter. That hive will survive when a hive with less capable workers might not. And that’s enough. The new queens from the surviving hive will carry the altered gene and it’ll be present in the workers of the new colonies those queens create. The altered colonies will also survive in slightly colder places than before so will succeed at slightly higher altitudes and in slightly cooler climates.

The worker honeybee in the photo is collecting pollen. Insect-pollinated plants have slightly sticky pollen that lodges on the bee’s hairy body. Bees visit flowers to collect nectar from the base of the petals, but get dusted with sticky pollen in the process. Bees clean themselves like most insects (you’ve probably seen houseflies doing it, sweeping off particles of dust with one leg while standing on the others). When bees clean themselves, most of the pollen end up stuck together as a lump and lodges on a series of special hairs on the hind legs. Look closely and you can see this bee’s pollen load on its rear leg; an orange/yellow colour. Pollen is protein rich and the bees feed it to the bee pupae in the hive.

The plant feeds the bees nectar for energy and pollen for growing young bees; while the bees move pollen from flower to flower, and often from plant to plant over quite long distances, sometimes a mile or more. So the bees and the plants both benefit, it’s a useful co-operative effort.

If the Universe did not include time, nothing would change and there would be no patterns, no life, just stasis.

What’s in an image? Sometimes quite a lot, more than meets the eye. I’m posting an image every two days or so.

Anemones are simple flowers, but beautiful! I have strong childhood memories of the white version of these growing in my grandfather’s garden in Cirencester. They managed to grow in small cracks between the bottom of the house wall and the stone paving. The flowers stood nearly as tall as me so I suppose I might have been between five and seven years old at the time.

The flowers in the photo are at various stages of development:

On the stem just right of the centre you can see a few tiny leaves and a little, pale-green flower bud.
In the centre, near the top, is a much larger bud, about to open.
Right down at the bottom, a flower has opened but the petals are not yet full size and have not developed their final colour.
The flower on the left and just below the centre is fully open. There’s a little insect sitting on its centre.
Below and right of it is a more mature flower, the yellow anthers have shed their pollen and have shrivelled.
A little above and right again is an even older flower, the anthers are in worse condition and some of the petals are damaged around their margins.
The flower in the upper left has lost most of the anthers and the petals look tired and old.
In the upper-right you can see a flower with only two petals remaining.
And just above, the yellow globe is the remains of a flower that has lost all of its petals.

Although they look like pink petals, and I’ve called them that here, botanically speaking these are actually modified sepals. On most flowering plants, the sepals are small and green, normally hidden by the petals.

Patterns of development

The flowers on this Anemone are just one example of the kinds of patterns that come from anything that grows. We’re all familiar with the pattern in humans – fertilised egg, foetus, baby, toddler, pre-teen, young teen, adolescent, young adult, mature adult, early middle age, late middle age, elderly.

And you can trace stages of growth in cities, technology, philosophy, civilisation, language families, culture, stars, wars, galaxies, you name it. Such patterns of development are a fundamental part of the way things are in our universe. Time ticks by relentlessly, and all these patterns are patterns of change, in other words evidence of the passage of time.

If the Universe did not include time, nothing would change and there would be no patterns, no life, just stasis.
