How can natural selection lead to regression?
In the genetic sense, it can't. Evolution really has one direction, and one direction only: forward. However, evolution may cause organisms to evolve traits that resemble traits of some of their precursors. For instance, whales are sea-mammals that descended from land-mammals, which in turn evolved from earlier aquatic organisms like fish. But due to the demands of their environment, whales evolved an overall morphology that resembles those of these earlier fish.
Are mammals organism?
Yes, mammals are organisms. Mammals are a diverse group of warm-blooded vertebrates that have hair or fur, give birth to live young (as opposed to laying eggs), and typically nurse their young with milk. They are found in various habitats around the world and play vital roles in ecosystems.
How comparative morphology support theory of evolution?
Look to the morphologies of all mammals and see rather easily how closely related they are in comparison to the more distantly related morphologies of all reptiles. Ancestral traits, such as tetropodal arrangement of limbs and then derived differences between mammals and reptiles. Reptiles having scales and mammals having hair.
What are the dominant organisms or the tertiary period?
During the Tertiary Period the dominant organisms were mammals. These mammals included the many different types of dinosaurs that were roaming the earth 65 million years ago. Other organisms included bony fish such as bass and trout, flowering plants, insects, and birds.
What key morphological feature is used to classify organism's as mammals?
Mammalae, or breasts.
How are anatomical features used to classify organisms?
These features were used to classify organisms before the development of DNA analysis. This way, scientists were able to look at certain morphological traits to classify the organism and then correlate them to their closest relatives. For example. Although bats are a lot like birds, certain morphological traits allow them to be classified as something other than birds. i.e. they are mammals - they have similar bone structure to most mammals In this regard, it is based traits other than their wings that they are classified as mammals, and not birds.

What The first attempt to classify living organisms was made by .?
Aristotle made a classification of living things. There were probably others earlier than him, but his is fairly sophisticated. He classified whales as mammals, for example.
Could you use a taxonomic key to classify animals that are not mammals?
YES

Are most non mammals organisms too?
It depends on what you mean by non-mammals. If you are counting all matter as a non-mammal, then most non-mammals are not organisms. If you are counting a non-mammal as any life form or any animal that is not a mammal, then all non-mammals are organisms.
What typ of organisms are deer?

Do all mammals rely on other organisms?
yes
