How do a group of organisms that are separated from the rest of its species evolve different traits?
They evolve and adapt so they have traits hat are useful to them, by Natural selection. This means that members of a species that are isolated, well, natural selection makes those with the best chances for survival mate with each other and produce offspring with that trait.
Why do some animals lay eggs in large number?
To increase the chances of survival of the species
Explain the difference between artificial and natural selection?
Artificial selection is anthropogenic -- humans interfere with nature to determine what traits get passed on, whereas natural selection is when through sexual reproduction the traits passed on are determined by survival of the fittest.
How did humans become such a powerful species?
Because we have certain traits that allow us to adapt and modify parts of the environment to increased are chances of survival.
What are the risks of inbreeding tigers?
Inbreeding in any species weakens the genetic structure of the offspring and makes them weak and susceptible to infectious diseases. This can result in a comparatively weaker generation of species which may result in extinction too.
How does natural selection influence mimicry?
Quite simply, the better an individual is able to mimic its surroundings, the less likely a predator is to spot it. This gives it a better chance of mating and passing its genes on to the next generation.
How does natural selection enhance or reduce tha variability of a species?
Natural selection 'weeds out' defective genes through successive generations - this both enhances a species chances of survival, and reduces variations in the species genetic make-up.
Does natural selection affect the survival of an individual or a species?
species
What increases species chances of survival?
By adapting to the climate and habitat.
According to Darwin what determines a species survival or extinction?
Natural selection.
True or false a mutation is helpful if it improves the chances for survival of the species?
false

Why is seed dispersal is important?
To expand the natural range of the plant species.
Does the storage of sperm in a female crayfish throughout the winter increase the chances of the survival of the species?
yes it does
Why do some organisms reproduce both asexually and sexually?
The strategy increases chances of survival for that species.
How does natural variation affect evolution?
Natural selection (the driving force of evolution) is the selection of genetic variations by how they effect the organism's chances of survival or reproduction. If they diminish it's chances, the organism or it's immediate offspring die and the gene is gone. If the genetic variations increase it's chances, then it survives. Without genetic variations there can be no evolution. Natural selection is the selection (by environmental pressures) of those variations.
