A. What are the 2 main reasons for variation between organisms of the same species? Nam lacinia pulvinar tortor nec facilisis. In allopatric speciation, groups from an ancestral population evolve into separate species due to a period of geographical separation. One of the requirements for the process of natural selection to occur is that there be variation among organisms. 2 years ago, Posted But if the malesor the preferences of the femaleswere to change, the species are still closely enough related that they could probably still mate successfully. Why or why not? Why do humans try to save and treat every human life while other creatures are selected by natural selection? As you know, the scales of these changes are different. Unlike Darwins finches, in which environmental conditions such as food supply rewarded birds with different beak shapes, the capuchino finches all eat the same type of food and live in grasslands scattered across South America. Yes, all individuals can change a little and pass those changes on to their offspring Yes, some individuals can change a little and pass those changes on to their offspring Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring No, species do not change even after many generations, so individuals of the same species would not look different Submit. Which of the following is TRUE about how environmental conditions have changed since the time life began on earth? Are there such height differences in the animal kingdom?
