Concept explainers

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

Human embryos pass through embryonic stages inherited from their ancestors. C. Developmental mechanisms are evolutionarily modified in a way that is unique to an organism’s way of life. 2. Which comparative anatomy example does NOT support the theory of evolution? A. Bats, humans, and cats have similarly constructed forelimbs and thus suggest a common ancestor. B. The genus of legless lizards are no longer considered lizards and are now part of the snake genus. C. Vestigial organs are structures that are no longer necessary for survival and are thus gradually becoming nonfunctional and reduced in size. D. All statements support the theory of evolution
6. Organisms classified as “birds” share a common feature. What shared derived character defined this taxonomic group? 7.

Keratinized skin helps prevent water loss in terrestrial environment. A. what type (or form) of Keratinized epidermal structure represents the ancestral character state of all reptiles, birds, and mammals?
Birds are unique because they have modified forelimbs which serve as wings and a body covered in feathers. However, just having wings and feathers does not mean that an organism can fly (look at the ostrich and penguin!). Please discuss at least 3 of these additional characteristics/adaptations that are required in order for birds to fly.
