Answer:
There are many types of evidence which support the theory of evolution such as comparative anatomy, fossil records, phylogenetic relationship, embryology et cetera
Comparative anatomy includes homologous organs and analogous organs. They support divergent and convergent evolution respectively.
For example, the homologous structure of limb of humans, birds, bat, horse, whale et cetera show that they are made up of the same set of bones which are humerus, radius, ulna, carpals, metacarpals, and phalanges.
It shows divergent evolution and supports that these organisms have evolved from a common ancestor.
Embryological evidence: When early stages of embryological development of different organisms are compared, it is found that these stages are similar at different levels of development.
For example:
- The appearance of pharyngeal-arch (gill-like structures) in vertebrates during embryo development.
- Salamanders and terrestrial frogs pass through larval stages within an egg. They possess the features similar to aquatic larvae, however, when they hatched out the eggs being ready for life on land.
The<em> cell membrane</em> controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.
Answer:
C) In 1946, the Argentinian government imported fifty beavers from Canada, which were to be released in Cami Lake with the intention of creating a commercial fur trading industry. Though a viable industry ultimately failed to materialize, the introduction of the beavers into the region has had far-reaching consequences.
Answer:
Polyphyletic relationships .
Explanation:
The primary goal of modern systematics is construct 'family trees' that exhibit polyphyletic relationships because systemics deals with grouping or organising living organisms into groups base on biological meanings of function and polyphyletic relationships which is organising or grouping of organisms that don't have common ancestors Into different groups or unrelated organisms.
