C is correct |
|
A phylogenetic tree (also phylogeny or evolutionary tree [3]) is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree, indicating common ancestry. |

C is correct |
|
A phylogenetic tree based on rRNA genes, showing the three life domains: bacteria, archaea, and eukaryota. The black branch at the bottom of the phylogenetic tree connects the three branches of living organisms to the last universal common ancestor. In the absence of an outgroup, the root is speculative. |

A. true
B.false as we cannot make a conclusion that they live only for short period of time
C. true
D. False since this statement is likely to be irrelevant. |

Kin selection, a type of natural selection that considers the role relatives play when evaluating the genetic fitness of a given individual. It is based on the concept of inclusive fitness, which is made up of individual survival and reproduction (direct fitness) and any impact that an individual has on the survival and reproduction of relatives (indirect fitness). |

A is correct |
|
Since mutated male mouse has chromosomal deletion so the number of degeneration after implementation would go high. |

A is true
B is true
C is false
D.may be both true and false since climate change can not only increase the speciation rate but also decrease speciation rate too. |

Many studies have tested whether concerted shifts in speciation (cladogenesis) and morphological evolution occur through time during adaptive radiation or after mass extinction within single groups3,4,5,6. However, we know little about the extent to which these rates are coupled across multiple contemporaneous lineages and the effect of this coupling on standing patterns of biological diversity. The theory of punctuated equilibrium proposed that morphological change typically occurs in association with speciation events7,8, but palaeontological tests of the model have typically focused on patterns of morphological change associated with particular speciation events9,10 or general patterns of morphological stasis through time11. |
Rates of speciation and morphological evolution are correlated across the largest vertebrate radiation
