What may have occurred to prevent species that are of the same grade from also belonging to the same clade?
similar structures arising independently in different lineages, convergent evolution among different lineages, and adaptation by different lineages to the same selective pressures
What do gradualism and punctuated equilibrium have in common?
Punctuated equilibrium is commonly contrasted against phyletic gradualism, the belief that evolution generally occurs uniformly and by the steady and gradual transformation of whole lineages (called anagenesis). In this view, evolution is seen as generally smooth and continuous.
How do an organism's adaptations help it survive?
Actually the question has things a bit out of order. Adaptive mutations turn out to confer enhanced fitness (for survival) attributes which are passed to offspring. At some point creatures of such lineages become genetically isolated and able to reproduce only among themselves. It is only in that ancestral sense that inherited "adaptive traits" can be called helpful in the present time.
What is the best summarized concept of natural selection?
organism best adapted to their environment survive- apex
How do adaptive radiation and convergent evolution differ?
Divergent evolution creates the divergence of a single species by isolating the gene pools of each species thereby increasing the differences between the population and eventually species. Divergent evolution is the evolution of different species from a common ancestor (and hence common characteristics) to attain new, dissimilar characteristics. Convergent evolution works on a different level. Unlike divergent evolution, convergent evolution does not create species with similar derived characteristics. Convergent evolution involves the adaptation of several different, unrelated organisms to the same environment in the same way. For example, flies and birds are not immediately related yet they both cope with getting around by flying with wings- similar structures that are not derived from one and other. Convergent evolution does not create new species, unlike divergent evolution. Convergent evolution is the co-evolution of different species with different ancestors in such a way that they attain the same characteristics independently of each other.
What does Hadero mean when she uses the term and ldquosonic lineages and . What does she describe as her own sonic lineages?
What does Hadero mean when she uses the term, "sonic lineages". What does she describe as her own sonic lineages?
What is the word for a group of lineages?
The term meaning "a group of lineages" is a clan. A lineage is a group of families descended form a common ancestor.
What may have occurred to prevent species that are of the same grade from also belonging to the same clade?
similar structures arising independently in different lineages, convergent evolution among different lineages, and adaptation by different lineages to the same selective pressures
How does evolution lead to the tree of life?
Evolution is a process of continuous divergence. A lineage splits, producing two or more diverging descendant lineages. Each of these lineages may then produce more diverging lineages, like branches stemming from a trunk. As such, a tree structure nicely represents the plot of diverging lineages and their ancestors. Hence, the so-called "tree of life".
Which is strong evidence that similar traits in different evolutionary lineages are the result of homology and not homoplasy?
The traits are also found in many intervening lineages on the tree of life
What are found in all protists lineages?
Mitochondria
Who are the headmonks of Tibetan Buddhism?
The head monk of Tibetan Buddhism is the Dalai Lama. Each of the four major lineages (as well as some minor lineages) have their own head as well.
What term is used for an animal with cells from 2 different lineages?
chimera
What considers characteristics that have arisen as lineages of organisms have evolved over time?
Unanswerable.
What is divergence in evolution?
Divergence is the growing apart of two lineages - lines of descent. Divergence may occur at the morphological, behavioural and developmental level, and will always occur at the genetic level, at least when two lineages are reproductively isolated from one another.
How many printers did it take to print?
16 according to the druid accounts in the Greek and Norse lineages
What is an ancestral shrine?
An ancestral shrine is a temple dedicated to deified ancestors and progenitors of surname lineages.
