Evolution is a change in the heritable characteristics of biological populations over successive generations. Let's take this quiz now!
There are patterns in the fossil record that suggest other species have diverged from a single ancestor species
There are biogeographic patterns in the distribution of species, for instance distinct bird species on an island tend to resemble one another, suggesting a common ancestor.
There are common stages in the early embryological development of organisms representing several distinct vertebrate groups.
Anatomical structures, such as forelimbs, in different groups appear to be modified versions of structures that might have been present in a common ancestor .
All of the above.
Natural selection is also a random process
Natural selection is nevertheless a directed process- the likelihood one variant will be favored in a given environment over another is predictable, even if the origin is not.
There is no possibility God could be involved in this process.
A, B and C.
E. None of the above.
Male peacocks evolve tail feathers that would appear to make them more rather than less vulnerable to predators.
Male deer evolve antlers that are not used to defend themselves against predators.
A bird issues a warning cry that puts it at greater risk of being noticed by a predator
Some traits appear to have no adaptive value
All of the above
an important mechanism of biological evolution is natural selection
New alleles arise through mutation
Evolution is the change in gene frequencies over time
Genes are the units of inheritance
characteristics acquired during an individual’s lifetime can be passed to its offspring
Here's an interesting quiz for you.
