The relationship between DNA sequences among species did not match relationships between skeletal patterns, casting the most doubt on the relationships depicted by an evolutionary tree.
A phylogeny is another name for an evolutionary tree. A phylogenetic tree is a branching tree that depicts the evolutionary relationships of distinct biological species based on morphological and genetic similarities and variances. All life on Earth is represented by a single phylogenetic tree, reflecting a common ancestor.
The branching structure in phylogenetic trees demonstrates how species arose from a common ancestor.
Facilitated diffusion refers to the process of spontaneous passive transport of molecules across a biological membrane via a specific transmembrane integral protein.
