안녕하세요 ^^
1. What's the difference between a phylogram and a phylogenic tree?
오, 보통은 what's the difference b/w phylogram and cladogram 으로 묻던데.. 그래서 다 답하겠습니다.
phylogenetic tree or evolutionary tree is a branching diagram showing the evolutionary relationships among various biological species or other entities
그중에서 자세히 들어가면 여러 종류의 tree를 subdivide 할수 있는데요..그중에서 두개만 얘기하자만
-
A cladogram is a phylogenetic tree that only represents a branching pattern; its branch distance do not represent time or relative amount of character change.he shape indicating relatedness.
It shows that, say, humans are more closely related to chimpanzees than to gorillas, but not the time or genetic distance between the species.
-
A phylogram is a phylogenetic tree that has branch distance proportional to the amount of evolutionary distance, whether based on genetics or characteristics.
2. Do we have to know scientists who discovered animal behaviors (ex. Tinbergen, Frisch, etc.) and know what they discovered?
No. Scientists' names you should know would be Mendel, Watson and Crick, Rosalinda franklin, Darwin, Miller and Urey.
3. Deuterostome이 정확하게 무슨뜻인가요? Mouth & anus 이렇게 구멍이 2개가 있다는건가요? I thought since those two are connected it counts as one opening?
In the process of development, blastopore가 first opening 이 되는 데요, 그게 mouth가 되면, protostome ( first mouth) 이고
그게 anus 가 먼저 되고 mouth 는 나중에 그 반대 편에 생기면 , deuterostome 이라고 합니다. ( deuterostome 을 two opening 이라고 하지 말고, second mouth 로 외워야 안헤깔립니다.
first opening becomes anus , and second opening becomes mouth) echinoderm , chordata 가 deuterostome 에 속합니다.
protostome 중에서도 반대편에 anus 가 생겨서 two opening 인 애들도 있거던요 ^^ ( nematode, mollusc, annelid, athropoda)
시험 잘 보세요! ^0^
