What else can I help you with?
Biologists use molecular clocks to try to measure?
Generally, a molecular clock is used to describe the rate of molecular change over time that tells you when two species, or taxa, have diverged.
What is the definition for rapid evolution?
Rapid evolution is where the subjective species in a population is considered to be evolving in an unusually high frequency and rate, thus 'rapid' evolution is occuring.
Does the extent of sexual dimorphism in a species affect the rate of evolution in that species?
Perhaps, coupled with sexual selection. Take the elephant seal. The preference of females for large males to head the harems drove the evolution of larger and larger variance in the size of the males to the females and rather quickly.
Do variations in populations lead to new species?
Variations in offspring are acted upon by natural selection: some offspring will be slightly more proficient at producing new offspring than others. This means that some alleles will promulgate throughout the population gene pool at a faster rate than others, resulting in a shifting frequency of incidence in the population gene pool. This is what evolution is: shifting allele frequencies in the population gene pool.
Why can bacteria evolve so quickly?
Insects and bacteria are said to evolve faster than some more complex animals because they reproduce faster. Simply put the more offspring you can make, the faster they mature and make new offspring with selected genes, then the faster they can evolve.
Can a species that reproduces at a slow rate such as a whale that produces one offspring every six years still overproduce?
no
Why do exotic species displace native species?
Often the exotic species has fewer natural enemies in the new environment but competes for the same food supply and other necessities as the native species it displaces. Sometimes the exotic species is more adaptable or more aggressive and so pushes out a native species. Sometimes the exotic species reproduces at a higher rate or more successfully than does the native species.
Does evolution occur faster in an organism that reproduces sexually or asexually?
Depends entirely on the rate of reproduction.
How does the COX1 protein still functionif the COX1 gene is altered between species?
The COX1 protein can still function if the gene is altered between species due to its high rate of mutation as well as the fact that its sequence is conserved.
How does rate of extinction compare to the rate of species formation on earth today?
The rate of extinction is faster.
How does the rate of extinction compares to the rate of species formation on Earth today?
The rate of extinction is faster.
How does the rate of extinction compare to the rate species formation on earth today?
The rate of extinction is faster.
How does the rate of extinction compare to the rate of species formation on earth today?
Currently, the rate of extinction is significantly higher than the rate of species formation on Earth. Human activities, such as habitat destruction, climate change, and pollution, have accelerated the extinction rate. This imbalance in the rates of extinction and species formation is leading to a loss of biodiversity at an alarming rate.
What is the rate of disappearance of the endangered species in the region?
The rate of disappearance of endangered species in the region is currently high, posing a significant threat to their survival.
What has a species reached when its birth rate is equal to its death rate?
Carrying capacity
What rate do organisms die?
depends on what species it is
What controls the rate of species survival?
biodiversity
