The first man to use fire was
Homo erectus is known to have been the first hominin to use fire. Evidence from archaeological sites suggests that Homo erectus used fire for cooking and warmth, which represents a significant evolutionary advancement.
Human evolution actually started in
Human evolution is widely accepted by scientists to have started in Africa. The earliest known hominins, the ancestors of modern humans, have been found in Africa. This region is often referred to as the 'Cradle of Humankind' because it is where the earliest fossils of human ancestors have been discovered.
Peking man is known as
Peking Man is known as Sinanthropus. The term 'Sinanthropus' was used historically to describe fossils found near Beijing, China, which are now classified as Homo erectus. The fossils date back to approximately 750,000 years ago and are an important part of the study of human evolution.
Which of the following is correct match regarding cranial capacity and location of respective
Australopithecus is known to have lived in Africa with a cranial capacity ranging from 450 to 600 cubic centimeters (CC). This genus is one of the earliest known ancestors of modern humans, and its fossils have been found primarily in Eastern and Southern Africa.
Which one of the following ancestors of man first time showed bipedal movement ?
Australopithecus is considered one of the first ancestors of humans to show bipedal movement. Fossil evidence indicates that they walked upright on two legs, which is a significant evolutionary step in human ancestry.
One of the oldest, best preserved and most complete hominid fossil commonly known as ‘Lucy’ belongs to the genus.
The fossil commonly known as 'Lucy' belongs to the genus Australopithecus. Lucy is one of the oldest, best-preserved, and most complete hominid fossils, discovered in Ethiopia in 1974. Her species is specifically Australopithecus afarensis.
Which one of the following pair of items correctly belongs to the category of organs mentioned against it?
In annelids like Nereis, earthworm, leech etc the tubular coiled structures called nephridia are excretory organs. In phylum-Arthropoda, insects, centipedes, millipedes and arachnides possess Malpighian tubules as their principal excretory organ.
Analogous organs have almost similar appearance and perform the same function but develop in totally different groups and are developmental origin, eg, wings of butterfly, birds, bats.
The homologous organs have common origin, perform varied functions and have different appearance, eg, thorns of Bougainvillea and tendrils of Cucurbita.
Vestigial organs are useless remnants, which might have been lagre and functional in the ancestors, eg, nictitating membrane, venmiform appendix, etc.
The ultimate source of allelic variations is:
This makes mutaion is the most important evolutionary agent as it introduces new alleles into the gene pool of a population increasing variation.
People who carry an allele for normal haemoglobin and an allele for sickle cell are resistant to malaria. They are examples of:
Answer 1. The heterozygote does not develop severe malaria and severe anemia as well.
In a population of red (dominant) and white flowers, the flowers of red flowers is 91%. What is the frequency of the red allele?
Answer 4. The white flowers are 9% or the frequency of the recessive allele would be 0.3 or 30%. The frequency of the dominant allele would be 70%
