the actions of organisms as they use or fail to use body structures.
That no species is stable, and that all species become extinct in time. That includes us.
The morphological species concept differentiates species by their physical traits, basically. The biological species concept defines a species as generally organisms that breed with others of the same species; rather a genetic isolation concept. The phylogenetic concept is based on evolutionary relationships and is the concept used by cladists.
Evolution is always happening. Species are constantly changing to adapt to their surroundings. If evolution wasn't always happening, many different species would have died.
Divergent evolution:)
On Origin of Species is his most famous work, and this is the book most commonly discussed when speaking about Darwin.He had several books however, some of which were fairly controversial.
Biological species concept, phenetic species concept, reproductive competition species concept, evolutionary species concept, and the recognition species concept.
It doesn't. It supports creation.
how variations occur within a species
Lamark's theory incorporated this concept though Darwin picked up on it and used it in his seminal work. The concept is the use and disuse concept.
The cast of On Hyperlinkage and the Evolution of the Species - 2005 includes: Matthew Clayfield

He demonstrated the concept of evolution in his book, the Origin of Species. He also made another book about his trip among the HMS Beagle. Evolution
It's not so much the organism or a type of organism that is difficult to define as a species but rather the differences in the theories regarding the definition of the word 'species'. For example the Biological species concept and phylogenetic species concept can be at odds when looking at convergent/parallel evolution.

Physical, or biological anthropology is the coherent half of anthropology and is underlined by the concept of evolution and the theory of evolution by natural selection. Physical anthropology concerns itself with comparative studies of simian and prosimian species and the evolution of the human species. So evolution is the change in allele frequency over time in a population of organisms in physical anthropology as well as anywhere in the world.
Evolution is a change in species over time.
The main difference between the typological species concept and the morphological species concept is that the typological species concept classifies organisms that share characteristics that set them apart from others, whereas the morphological species concept classifies them as the same species if they appear identical.
