Descent with modification
Descent with modification
The concept is evolution, which is the process by which living organisms change and adapt over time through genetic variation, natural selection, and other mechanisms. This results in the development of new species from common ancestors.
The principle that living species descend with changes from other species over time is referred to as evolution. This idea was proposed by Charles Darwin in his theory of evolution by means of natural selection.
The principle that living species descend with changes from other species over time is referred to as "evolution." This concept suggests that through mechanisms like natural selection, genetic drift, and mutation, species adapt and evolve over generations. It forms the basis of modern biology and explains the diversity of life on Earth. Charles Darwin is often credited with popularizing this idea through his theory of natural selection.
This concept is known as evolution, as proposed by Charles Darwin. It suggests that all living species have a common ancestry and have evolved over time through a process of natural selection, where organisms with advantageous traits are more likely to survive and reproduce. Evolution is supported by various forms of evidence, including fossil records, comparative anatomy, and molecular biology.

Biological species concept, phenetic species concept, reproductive competition species concept, evolutionary species concept, and the recognition species concept.
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.
Individual organisms differ, but some of this variation is heritable. Species alive today are descended with modifications from ancestral species that lived in the distant past.
There are about 200 or more different species. Ur welcome!
Ecological species concept.
They can't. Once a species becomes extinct, it has reached the end of the line. It no longer exists, so therefore produces no more offspring. Thus, the theory that living species of today are descended from extinct species from long ago is untenable.
