Still another reason to accept Darwin’s Theory is the geographic distribution of species, meaning that certain plants and animals have evolved in specific ways to meet the needs of their isolated environments.

Another reason to support the theory of evolution is the fossil record of change over time throughout earlier species.

For all those reasons, Darwin’s Theory of Evolution makes One interesting fact that involves the anatomical similarities between organisms is between dogs, wolves, and other members of the genus Canis.

Wolves and dogs both share a distant relative, and shockingly they share 99.8 percent of their genes!

That’s a shocking total and a staggering amount of evidence for the theory of evolution to be accepted throughout the whole scientific world.

Two other species that share anatomical similarities are birds and dinosaurs.

” must be recognized as different from the question, “How can species X cope with problems threatening its current existence?

” The first question is inherently about the relationship between the organism and its environment and arises primarily when the current environment becomes different from the EEA.[5] To provide a concrete example, imagine a lizard species adapted to live in the rainforest that is suddenly transported to the desert (alternatively, the lizard can stay where it is and the climate can change).

Any given phenotypic trait therefore cannot be analyzed in isolation from other traits, but rather as part of a genetically influenced developmental system.[3] Nikko Tibergen, who shared the Nobel Prize in 1973 for helping to found the science of ethology, stressed that four questions must be addressed to fully understand any particular trait: (1) Why does the trait exist, compared to many other traits that could exist, often (but not always) based on the winnowing action of natural selection? (3) How did the trait evolve over a period of generations?

(4) How does the trait develop during the lifetime of the organism?
