Which species has the most varied physical features? The domestic dog is a varied example. The person is Teri Robertson.

I remember one of my university tutors telling me that mammals and all other animals were too boring to study. Look at the incredible variation within a single species of ant or scurvy. There will be giant soldiers in one colony that are half their size. They will have wings of their own. Until they mate and find their own family as an engorged, egg-laying machine, the reproductive females do as well. There is a person named Lulu Bradley.

There is Brassica Oleracea, which is also known as cabbage, broccoli, collard greens, kohlrabi, and so on. The same species.

‘Brassicas make up the mainstay of our winter eating.’

Great brassicas can be grown from cabbages to brussels sprout.

The people are humans. It is possible to carry victims from forest fires. One is too weak to carry a gum wrapper outside.

Dog breeds look different because they have been bred to look good and to be useful. After a few generations, dogs would still have some differences, such as size, but they would be less so than before.

Social insects include ants, wasp and other arthropods. There are huge physical differences between the sterile female workers and the males within the same species. The insects have young that are physically different from the adults. There is a randomusername222.

It's hard to pin down the whole concept of species. Taxonomists used to separate things into different types on the basis of the same type. The most-used definition right now is based on the ability of members of a species to breed with each other, but I am not sure how we would know which beetle species could interbreed.

Sexual dimorphism, where males and females differ greatly, is just a population reacting to some evolutionary pressure.

We mucked about with the genetics of the dogs. I don't think about this too deeply for horses and shetland ponies.

I don't think any natural situation would cause the same level of difference, but if it did, the biologists would probably define many species before the geneticists had done their homework. It is semi functional.

Did you mean apples? Mr.Cassandra.

You are comparing them with fruit.
