We examined the biogeographic patterns implied by early hominid phylogenies and compared them to the known dispersal patterns of Plio-Pleistocene African mammals. All recent published phylogenies require between four and seven hominid dispersal events between southern Africa, eastern Africa, and the Malawi Rift, a greater number of dispersals than has previously been supposed. Most hominid species dispersed at the same time and in the same direction as other African mammals. However, depending on the ages of critical hominid specimens, many phylogenies identify at least one hominid species that dispersed in the direction opposite that of contemporaneous mammals. This suggests that those hominids may have possessed adaptations that allowed them to depart from continental patterns of mammalian dispersal.
plz mark me as brainliest if this helped :)
Electronegativity.
If the difference in electronegativity for the atoms in a bond is greater than 0.4, we consider the bond polar. If the difference in electronegativity is less than 0.4, the bond is essentially nonpolar.
The correct option is D. Because uranium is a radioactive element, such run off is very dangerous to the people who are living in the environment where the spill occur. The run off must be isolated as soon as possible, by collecting it in a retention pond.
Like all other cellular membranes, the Plasma membrane consists of both lipids and protiens. the fundamental stracture of the membrane is the phospholipid bilayer, which forms a stable barrier between two aqueous compartments. these compartments are the inside and the outside of the cell.
That's all what I know I hope it will help u
