learnt about the classification of species using their common characteristics‚ but I realize that there are always exceptions. For instance‚ we know that mammals give birth‚ however there are those which lay eggs. Also‚ some of them have wings or fins instead of limbs. This‚ I feel‚ is the wonder of biodiversity. Although a number of new species are discovered and added into different families with millions of others everyday‚ less than one percent of all species that ever existed still exists today

Abstract Constructing a cladogram to determine the related species and the evolutionary history. Five mammalian species‚ which are dog‚ cat‚ horse‚ opossum‚ and deer‚ are distributed into cladogram based on morphological character and molecular data. This allows identifying the relatedness of these species. By their appearances of structures and behaviors‚ the dog and cat eat meet while deer and horse eat plants. This prediction leads to the hypothesis that car and dog are close whereas deer

I think that invasive species are invaders. An invasive species are living organisms that are non-native species in particular environment. In other words‚ it is an imported species that has a tendency to spread and is capable of damaging the environment‚ the human economy and human health. Some of these invasive creatures have caused the extinction of whole species and have caused irreparable damage to the surrounding ecosystem. For example‚ alien insects‚ organisms‚ plants cause damage to crops

Introduction Reproduction is a natural and normal thing in our day to day lives. Animals and humans reproduce offspring‚ all year round. Separation is usually the furthest thing from our minds. But‚ mother natural can always turn anyone’s world upside down. For Example

Many different plant and animal species thrive in the rainforest environment‚ but it is the trees that define the way we see the rainforest. From the air‚ a rainforest looks like an enormous‚ green carpet. The canopy very rarely breaks‚ with no gaps between the trees. Beneath these trees‚ there are thousands of different types of plants. Living amongst the trees‚ vines‚ shrubs‚ ferns‚ and mosses are many different types of animals. These range from the smallest ant to the carnivorous (meat-eating)

of controlling this invasive species includes decreasing the defragmentation‚ and the creation of edges in which the DSV and other invasive species like the garlic mustard may flourish (Foster and Sandberg 2004). By outcompeting the native species‚ the DSV and garlic mustard are a danger to the native grasses and plants. DSV disrupts the food webs and breeding patterns of the monarch butterfly and put the species at risk (Mattila and Otis 2003). Other invasive species can introduce disease and parasites

Every living organism on our planet‚ both plants (Flora) and animals (Fauna)‚ are included when determining biodiversity. On our planet‚ there are 13.6 million species of plants‚ animals and micro-organisms‚ and Australia has about 7% (one million) of these (Australian Museum‚ 2017). Australia has a vast biodiversity because it is classed as a ‘megadiverse country’. Megadiversity is when a country has high levels of biodiversity. One way to measure Australia’s biodiversity is by looking at taxonomic

be more successful in producing young (because they survive to adulthood). If there was no color variation‚ or if a predator that tended to pick the brightly colored fish was absent‚ then there would be no natural selection pressure driving the species towards more drab colors. Which of the following facts is least useful to a taxonomist trying to place animals in the same genus? Animals with shared ancestors have more DNA in common than animals that do not share ancestors.
