Generally, species.

In making the case for this view of counterfactual history, Bowler discusses the late evolutionary biologist Stephen Jay Gould’s study of the Cambrian fossils of the Burgess Shale that led him to conclude that if one could replay the tape of life, the evolution of species would be entirely different due to countless contingencies, so much so.

Meanwhile, phylogenetic analysis shows the new dinosaur is a basal member of the carcharodontosaurs—a term that means it.

14. The Formation of Species and Evolutionary Change 14.4. Evolutionary Patterns Above the Species Level A species is the smallest irreversible unit of evolution. Because the exact conditions present when a species came into being will never exist again, it is highly unlikely that it will evolve back into an earlier stage in its development.

Evolutionary psychology is a sub-discipline that tries to understand human behavior as a series of adaptive strategies, which are essentially behaviors that help a species survive. Basically.

Nov 21, 2007  · Evolutionary biology presents a bewildering array of phenomena to scientists and students alike—ranging from molecules to species and ecosystems; and embracing 3.8 billion years of life’s history on earth.

Evolutionary History The Narwhal, or Monodon monoceros , belongs to the Cetacean order. Traditionally, the theory of cetacean evolution was that whales were related to the Mesonychids, an extinct order of carnivorous ungulates (hoofed animals), which resembled wolves with hooves and were related to the Artiodactyls (even-toed hoofed mammals).

In terms of ecological functioning, the role of some species is irreplaceable and vital for many of the ecosystem services that human society is reliant on. Other species may not provide such ecological benefits, but are distinct in their evolutionary history and may act as a valuable source of evolutionary potential to maximise diversity.
