A scientist has discovered a new organism and wishes to classify it based on morphology and genetics. While he is waiting on the genomic data, he analyzes the morphological data. The new organism has homologous structures to birds and analogous structures to bats. However, he observes one trait that is shared with bats but not birds. What should he do?

tentatively group it with birds and speculate that the trait shared only with bats is a derived rather than an ancestral trait with bats.

Explanation:

The scientist after his observation should tentatively classify this organism with birds and the the second end of calculating the other morphological traits which makes it possess the likely bat traits to be ancestral.

According to scientists, most widely used modern systematic practice

depends upon the assumption that a change from character in one species

to character occurs once and once only in the evolutionary process and that this process is irreversible so that it never returns.

In this scheme, there are no independently derived parallel evolutionary changes,

nor convergences from a variety of states to a single one. Therefore, when two organisms share a

character state different from other species, it is because they are more closely related to each other through a recent common ancestor than they are to other species.

Also using the parsimony principle, a scheme of common ancestry for all the species is derived that uses all the characters that have been observed.

This species is phylogenetically related to birds (since it shares homology to birds) and is not evolutionary related to bats

Explanation:

The presence morphological analogies to bats but not present in birds are the product of an evolutionary process, these structures are defined as evolutionary novelties

meiosis is the first to occur after the nuclei of opposite of opposite mating types fuse

measuring physical properties lab reportinstructions: in the physical properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in tiny world. record your observations and test measurements in the lab report below. youwill submit your completed report.name and title: lyric lawton, mr.herbert, 10/13/17, physical properties lab. objective(s): i need to parvus build his house out of the right material, so he will stay cool in the mountains.hypothesis: if we use wood to build the roof of the house, then the temperature inside the house will remain cooler.if we use clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler.if we use aluminium to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.if we use iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
