I don't understand how there could be any difference between micro and macro evolution. Surely any life form large enough to contain genes would evolve in exactly the same way? The genes don't really care how big an organism is going to grow. Their job is simply to provide the blue print for the mor...

Hi Surgeon girl. What you have observed in old people is simply the result of the loss of the sexual hormones. People are not turning into the opposite sex. They are simply growing more similar physically because they no longer have the hormones that produce the secondary sexual characteristics. If ...

Hi Sideshow. It doesn't look like a cat to me. A bit too thin. Could be a monkey or as you suggest a musk deer, or, it could be just a piece of carved ivory, although, I suppose there is a hollow centre to it, at the top?

The only bones I can think of that curve like that are phalanges supporting claws or possibly part of a rib, although these ar not normally so smoothly round, Are you sure it is a bone?

This is not an unusual phenomenon. It is standard that fish eat their own fry, and the more overcrowded a population becomes the more fry get eaten,- until there are virtually none left and the population has to age and many die before there is room for more fry to grow. Either the fish themselves w...

The point is that if you have two species and you multiply the area by ten you should using basic maths get 20 species. But you only get four. So the actual equation that applies is one that is far more complicated than simple mathematics.

Re: Population ecology

If there are barriers the three populations could speciate, but, especially with reptiles and amphibians size is mostly dependent on availability of food. Where food is plentiful and good, size reaches an optimum. Other factors are temperature humidity, and possibly the ability to hide more easily. ...

wildlife gardening

I thought with the Chelsea flower show etc coming up it would be a good time to discuss the way to create a beautiful garden which still provides the best possible habitat for all wildlife. Most people think that the most beautiful can't be also the most useful but I would dispute this. I think that...

Re: biology urgent need help?

Er...you left out the time of day or year. The question is, one would expect insects to have some sort of biological clock going, by which they like to be in light or darkness for N hours. Their response should vary considerably according to the length of their exposure to artificial light.
