The binomial system

There are millions of species on our planet. Although species can be very different from each other, many have similar features that allow us to put them into groups. This is called classification.

Other classification systems

Cladistics is another way to classify organisms. It can use data from DNA or RNA sequences, rather than just physical characteristics. It emphasises the evolutionary relationships between different species.

Amphibians

Amphibians usually have lungs but they can also absorb oxygen through their moist skin. Their body temperature also varies according to their surroundings. Amphibians also reproduce by external fertilisation and lay eggs.

>Reptiles

Reptiles have lungs and dry scales. As with bony fish and amphibians, their body temperature varies according to their surroundings. However, reptiles reproduce by internal fertilisation and lay eggs.

Keys and identification

-

Keys are used to identify different species. A key will usually ask questions based on easily identifiable features of an organism. Dichotomous keys use questions to which there are only two answers. They can be presented as a table of questions, or as a branching tree of questions.

-

Branching tree example

-

This tree could help you identify a new vertebrate. For example, if it had no fur or feathers and dry skin, you would follow the right-hand pathway at the first and second junctions, but the left-hand pathway at the third junction. This would lead you to identify the animal as a reptile. -

-

Fur then mammal (ie badger). No fur but feathers then bird (ie owl). No feathers but dry skin, then reptile (tortoise). Moist skin and scales then fish. Moist skin no scales then amphibian (ie frog).
