1. Which of the following supports the theory that all modern human populations are descended from a single ancestral population that emerged in Africa?a. Comparative molecular studies trace our earliest genetic material to Africa.b. Stone tools found in sediments coeval with the earliest H. ergaster (just under two million years ago) are essentially identical with those made by the first stone toolmakers many hundreds of thousands of years before.c. H. erectus evolved in eastern Asia at quite an early date and one branch of the species migrated back to Olduvai in Africa.No human fossils are associated with the first stone tools known, from sites in \Kenya and Ethiopia.

Answer:

a. Comparative molecular studies trace our earliest genetic material to Africa

Explanation:

With the development of the genetics we have been able to come to new findings or confirm some suspicions when it comes to the origin of the humans. The genetic analyses of the human DNA and the other hominids that have died out, as well as out closest ''cousins'' in the animal kingdom, have shown that the earliest human ancestors have evolved in Africa. Over time, as the conditions allowed it, the hominids started to migrate out of Africa and gradually started to settle all around the planet.

Explain the impact of invasive alien plants on water availability

Answers

We review the current state of knowledge of quantified impacts of invasive alien plants on water quality, with a focus on South Africa. In South Africa, over 200 introduced plant species are regarded as invasive. Many of these species are particularly prominent in riparian ecosystems and their spread results in native species loss, increased biomass and fire intensity
and consequent erosion, as well as decreased river flows. Research on the impact of invasive alien plants on water resources has historically focused on water quantity. However, although invasive alien plants also affect the quality of water, this aspect has not been well documented. Alien invasive plants increase evaporation rates, and reduce stream flow and dilution
capacity. The biomass inputs of alien invasive plants, especially nitrogen fixers such as Acacia spp., alter nutrient cycles and can elevate nutrient concentrations in groundwater. Alien plant invasions alter the fire regimes in invaded areas by changing the size, distribution and plant chemistry of the biomass. More intense fires increase soil erosion and thereby decrease
water quality. In contrast to riparian invasions, aquatic invasive plants have been more extensively studied in South Africa and their impacts on water quality have been relatively well monitored. Water quality in South Africa is rapidly deteriorating, and all factors that influence this deterioration need to be taken into account when formulating actions to address the problem. The changes in water quality brought about by alien plant invasions can exacerbate the already serious water quality problems.
