Anatomy and embryology gives information on evolution. Anatomy deals with the study of the body structure of the living organisms including the humans. The study of embryos also gives information on evolution. For instance the things that will be present in a fully grown animal can be seen by monitoring the maturation of an embryo. The similarities in early stages disappear on development. For example, the human embryos have a tail like structure at a certain stage of development and gills at one of the stages. The two pair of slits of the gills disappears with the growth of embryo and final pair becomes ear and eustacian canal. This is evidence that humans had tails long ago and also had gills indicating that in the past we were aquatic or marine species.
Embryology gives an idea on how an organism looked at earlier stages. This study supports evolution. The developmental stages of several organisms when studied was found that they are very similar indicating they have evolved from a common ancestor. The anatomy of homologous features in organisms show common ancestry and thus supports evolution.
Answer:
Answer: More humans consume more freshwater, more land, more clothing, etc. The more people on the planet, the more food you need to feed those humans. Which can also cause more deforestation to create more space.
Answer:
C. Only 1, 3 and 4
Explanation:
Deforestation is the process of cutting down trees by man, which eventually lead to the the sparseness of trees in otherwise forested areas. The reasons for cutting trees by man may include: habitation by man, clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing as well as mining of minerals.
Deforestation leads to many adverse effects on both man and his environment. These adverse effects include:
Loss of biodiversity in the forests which may lead to extinction of species.; when forest areas are cleared, plants and animals who live in these forests lose their homes and some may eventually die off due to inability to survive in other habitats
Increase in temperature of the earth: Trees serves to cool the earth by removing some gases which cause heating of the earth from the earth. Such gases include carbon dioxide. When these tree are removed, these gases accumulate in the atmosphere leading to increase in earth's temperature.
Also, since tree absorb some gases while releasing others into the atmosphere, when these trees are cut, there would be an imbalance of these atmospheric gases.
