Species evolve independently possibly due to geographical isolations or behavioural isolations.
Geographical isolation includes the isolation of 2 groups of the same species. Since these 2 groups live in different locations, (e.g. a volcanic eruption resulting in a barrier between one side of an ocean and another side of the ocean), they will have different selection pressures in their different environments as well (e.g. one side of the ocean may have more sunlight and thus more underwater plantations than the other side of the ocean). Natural selection will eliminate those with disadvantageous characteristics (e.g. Fishes that only eat plants and nothing else on the side of the ocean with little plantations) with unfavourable alleles, and select for those with advantageous characteristics (e.g. Fishes are able to eat plants and other organic substances as well on the side of the ocean with little plantations) with favourable alleles.
Since the 2 groups have different selection pressures, natural selection will occur in different ways, selecting for and against different types of fishes with different types of alleles. Also, because of the barrier, they are not able to mate with each other, and there are no mixing of genes from one side of the ocean and the other side. They are genetically isolated. As genetic drift occurs over time, their gene pools become different from each other. Thus, they evolve independently.
Hope this helps! :)

If you look at the female cat's genital area,the space just under her tail,it will look like an upside down an exclamation mark (!) with the long slit of vaginal area below the anus. while the male cat has a narrow space between the anus and the penis, with the testicles in the middle... i hope u will understand!... :)
Eating regular meals establishes healthy eating habits, keeps you energized throughout the day, and can cause you to lose weight. regular eating habits establish healthy eating habits because it's always good to eat regularly. One of the biggest misconceptions to losing weight fast and in a healthy manner is by not eating, that is false. If you eat regular meals you can lose weight perfectly fine. The more calories you eat the more you lose, now i'm not saying eat a million and one candy bars, i'm saying if you eat food that is healthy can get you to lose weight. That also doesn't mean live off of carrots and strawberries for a week! You have to eat normally. So a peanut butter and jelly sandwich, pasta, rice or any kind of meat is the way to lose weight vs eating low calorie anything or a candy bar. Every type of food gives you energy! It all depends what it is too predict how much energy you'll receive or how long it will last. For instance, a candy bar will give you a lot of energy, fast but won't last as long as eating pasta or rice for energy. Eating regular meals does cause you to gain weight but thats a good thing, it gives you energy, muscle and can help you lose weight. Eating regular meals actually does the opposite of causing you to be hungry more often, it keeps you fuller for longer.
Both parents contributed a recessive allele and were short.
