- Question 10 Which data most strongly supports the "Out-of-Africa" hypothesis? A) Fossils found in Africa are generally smaller than those found on other continents. DNA sequences from extant African hominins are more diverse than extant hominins from other continents. The synapomorphy of hominins (bipedalism) indicates that ancient humans walked out of Africa. DNA sequences from extinct hominins are more diverse than extant hominins.

All the Single Ladies: Bdelloid Rotifers (Adapted from posts by Ed Yong, Not Exactly Rocket Science, 2009; Frances Farabaugh, Intern Invertebrate Zoology Department NMNH; and Hecox-Lea and Mark Welch BMC Evolutionary Biology (2018) 18:177) Bdelloid rotifers (pronounced with a silent "b") are a class of rotifers (approximately 450 species!) entirely made up of females. That's right, there are no male bdelloids. These females have been around without male counterparts, and consequently sex, for about 80 million years! The bdelloids pose a problem for evolutionary biologists, who have struggled to explain how these animals could make do without a strategy that serves the rest of the animal kingdom very well. The reason for these animals' evolutionary longevity is an area of continuing investigation amo scientists. Use what you know about how genetic diversity is introduced into a population to respond to the following questions: Explain why asexual reproduction is not…

Mark all answers that correctly describe this phenomenon. forelimb flippers hindlimb flippers These structures are convergent with hind limbs in other mammals as the whale has no ancestors with hind limbs. This is most likely the result of horizontal gene transfer between the whale and another organisms that has hind limbs, such as a sea lion. O The most reasonable explanation for this condition is a remnant of the ancestral mechanism for hind limb development, as cetaceans evolved from four legged ancestors. O These structures, when present, could be referred to as vestigial because they are a non-useful remnant of an ancestral structure that was once and important feature.
