Question

Short/Long answer type questions
Give the characteristic features that suggest a close phylogenetic relationship between man and apes.

Answer 1

Following characteristics, features suggest a close phylogenetic relationship between and the apes:-

• The apes and humans have essentially the same arrangement of internal organs, share all of the same bones (though somewhat different in shape and size), lack external tails, and have several important blood type systems in common.
  
• Humans and the apes have hands with thumbs that are sufficiently separate from the other fingers to allow them to be opposable for precision grips.
  
• Like all of the great apes, humans are sexually dimorphic--human men are 5-10% larger on average and have greater upper body muscular development. Like chimpanzees and bonobos, we are omnivorous.
  
• The DNA sequence and proteins that are formed after translation are very similar in apes and humans.
