Vertebrate embryos all follow a very similar developmental process. Which statement could explain this similarity? All vertebrates develop a backbone that protects the spinal cord. All vertebrates live in similar environments which require the same adaptations. All vertebrates inherit the same sequence of DNA from their parents. All vertebrates require the same nutrients during embryological development.

How can embryos help scientists understand evolution? Embryos go through various stages that suggest the animal’s evolutionary process. Embryos are frequently fossilized and illustrate change over time. Embryos provide evidence for which life forms existed at the same time. Embryos contain the code for all life on Earth.
Human embryos have tails which become tail bones before birth. Tails also appear in fish, reptiles, amphibians, birds, and mammals Humans also have hair and produce milk to nourish the young, which is unique to mammals. What does this indicate? a close evolutionary connection between humans and many other mammals a very distant evolutionary connection between humans and many other mammals a very distant evolutionary connection between humans and many other reptiles a close evolutionary connection between humans and many other reptiles
All vertebrate embryos have a tail and gill slits at some point during embryonic development. What does this suggest about vertebrates? These species evolved in similar environments. These species have the exact same DNA sequence. The embryos of these species require these structures to survive. These species share a common ancestor.
According to Richard Owen, the forelimbs of an adult human (with hands, adapted for grasping fruit from a tree), and the forelimbs of an adult bat (with wings, adapted for flight), are both derived from the same mammalian embryological structures, so they must represent: homologous structures, with similar embryonic anatomy, but different functions analogous structures, with different functions, and different embryonic anatomy analogous structures, with similar functions, but different embryonic anatomy analogous structures, with different embryonic anatomy, and different functions homologous structures, with different embryonic anatomy, but similar functions
All vertebrates (including humans) share all of the following anatomical traits except: O a body plan that is composed of an inner tube surrounded by an outer tube the left half of the body is essentially a mirror image of the right half a set of 4 limbs that are paired in both structure and function there is a hollow nerve cord running along the back pouches in the throat that correspond to the clefts between the gills of fish
The diagram shows various stages of embryonic development in 5 vertebrate species. Which of the following statements is supported by this diagram? salamander tortoise chicken human O Different animals go through similar stages of development during their embryonic stages. O Humans go through more stages of development than other animals. O The developmental stages of animals are very different: they have no similarities
As we progress through evolutionary time in the animal kingdom, certain trends emerge. Which is NOT a general trend observable in animal evolution? A general trend towards having a true body cavity A general trend towards asexual reproduction A general trend towards increasing tissue and organ development A general trend towards increasing cephalization
One reason that longevity may have evolved slightly differently in humans than in other species is that: our immune system is more advanced than that of most species. we have the ability to manipulate the environment. early hominids had significantly lower infant mortality that other, nonhuman primates. our bodies are larger than expected for our low metabolic rate.
Describe how the embryo changed from earliest stage to the latest stage of each animal.
Birds have all of the following features except: they have external fertilization always have two pairs of limbs they are homoeothermic they have feathers
Why do penguins, seals, and tuna havesimilar body forms that permit rapid swimming? all share a common ancestor at some point in the past. all of their bodies have been compressed since birth by intensive underwater pressures. flying, pregnancy, and gill-breathing all require similar adaptations in form. the shape is a convergent evolutionary adaptation that reduces drag while swimming. this is the only shape that will allow them to maintain a constant body temperature in water.
Which of the following is not a feature common to most animals? a. development into a fixed body plan b. asexual reproduction c. specialized tissues d. heterotrophic nutrient sourcing
