Charles Robert Darwin and Alfred Russel Wallace discovered the process of evolution called natural selection by Darwin.
There were several. Hitchcock used crows, seagulls and other seabirds.
A cladogram is a visual tool that displays evolutionary relationships among organisms based on shared characteristics. It helps to classify organisms into groups called clades, which consist of an ancestral species and all its descendants. By analyzing the branching patterns in a cladogram, scientists can determine the evolutionary history and relatedness of different species for classification purposes.
During Darwins visit to the Galapagos island he observed that these islands had many unique organisms, most of which were similar to but different from the plants and animals from the nearest mainland.... thus this indicated how population evolved. Darwin called this "descent with modification" meaning an ancestral species could diversify into many descendant species by the accumulation of adaptation to various environment. His observation described the theory of evolution.
Alien species or Non-native species .
adaptive radiation
Evoultion.
analogous structure
A radiation event. Called adaptive radiation.
The term that refers to the phenomenon of evolving different adaptive forms from ancestral species is called divergent evolution. This occurs when two or more related species become increasingly different over time due to adapting to different environments or ecological niches.

Hemlock tree are in the genus Tsuga, and there are several species. The Eastern Hemlock is called Tsuga canadensis, the Western Hemlock is called Tsuga heterophylla. There are several other species.
humans are part of incredible Species. The whole species is responsible.

Those organs are called vestigial organs. They are remnants of functional structures that were more developed in ancestral species but have decreased in size or usefulness in the current organism.
Characteristics that were present in the common ancestor of the entire group of organisms.This character state is called ancestral for the group as a whole.
A modified structure that is seen among different groups of descendants is called a derived trait. This trait has evolved from the ancestral form and is characteristic of a particular lineage or group of related species.
