Summary Introduction
Introduction:
The evolution is a process in which the changes occur in an organism’s characteristics within a population with time. Evolution explains the way living beings have changed over long period of time and have become the way they are.

Mammalian species possess an amniotic, a character state also inferred to have been present in the ancestor they share with Reptilia. Thus, this shared homologous trait is a______________of Mammalia.

PreviousNext
The two primates shown below both exhibit large eye orbits. One is a tarsier, the other is an owl monkey (the only nocturnal platyrrhine). Why do these primates share the trait for large eyes? Mark the best answer.
Group of answer choices
Random mutations, since having large eyes is abnormal in these species of primate.
Convergent evolution, since both separately evolved large eyes to adapt to a nocturnal activity pattern.
Both inherited this trait from their common ancestor, which was also nocturnal with large eyes.
Unclear, cannot determine from the information given.
Whereas most sarcopterygiians are oviparous (lay eggs), some sharks have viviparity (live birth) similar to that seen in mammals. This shared characteristic is an example of _______.
a homologous trait
an analogous trait
divergent evolution
a synapomorphy
an ancestral trait

Group of answer choices There are biogeographic patterns in the distribution of species, for instance distinct bird species on an island tend to resemble. Anatomical structures, such as forelimbs, in different groups appear to be modified versions of structures that might have been present in a common ancestor. There are common stages in the early embryological development of organisms representing several distinct vertebrate groups. Due to innate drive to improve, parts that are extensively used becomes larger and stronger and passed on to the next generation as seen on fossil records.arrow_forward

DIRECTIONS: Complete the paragraph about evidence of evolution by choosing the correct word provided below. biogeography fossils homologous molecular vestigial The theory of evolution states that modern species have descended from ancestral species through evolution and speciation. It is supported by a large body of evidence such as found in geologic strata. These are remnants of ancient life that provide evidence for the evolutionary change through now-extinct forms that led to modern species. Modern species retain certain structures that arose from a common ancestor structures. Other remnants of what was once useful to the ancestors are or the findings of the original distribution of related species across the Earth the connections between ancient evidence, DNA sequences have also shed light on the occurrence of such as structures. Furthermore, we can infer from the landmasses.
